The request_t 'handle' member is 32-bits wide, hence use wrt_reg_dword().
Change the cast in the wrt_reg_byte() call to make it clear that a regular
pointer is casted to an __iomem pointer.
Note: 'pkt' points to I/O memory for the qlafx00 adapter family and to
coherent memory for all other adapter families.
This patch fixes the following Coverity complaint:
CID 358864 (#1 of 1): Reliance on integer endianness (INCOMPATIBLE_CAST)
incompatible_cast: Pointer &pkt->handle points to an object whose effective
type is unsigned int (32 bits, unsigned) but is dereferenced as a narrower
unsigned short (16 bits, unsigned). This may lead to unexpected results
depending on machine endianness.

In NPIV environment, a NPIV host may use a queue pair created by base host
or other NPIVs, so the check for a queue pair created by this NPIV is not
correct, and can cause an abort to fail, which in turn means the NVME
command not returned. This leads to hang in nvme_fc layer in
nvme_fc_delete_association() which waits for all I/Os to be returned, which
is seen as hang in the application.

qlt_free_session_done() tries to post async PRLO / LOGO, and waits for the
completion of these async commands. If UNLOADING is set, this is doomed to
timeout, because the async logout command will never complete.
The only way to avoid waiting pointlessly is to fail posting these commands
in the first place if the driver is in UNLOADING state. In general,
posting any command should be avoided when the driver is UNLOADING.
With this patch, "rmmod qla2xxx" completes without noticeable delay.

The purpose of the UNLOADING flag is to avoid port login procedures to
continue when a controller is in the process of shutting down. It makes
sense to set this flag before starting session teardown.
Furthermore, use atomic test_and_set_bit() to avoid the shutdown being run
multiple times in parallel. In qla2x00_disable_board_on_pci_error(), the
test for UNLOADING is postponed until after the check for an already
disabled PCI board.

Annotate members of FC protocol and firmware dump data structures as big
endian. Annotate members of RISC control structures as little endian.
Annotate mailbox registers as little endian. Annotate the mb[] arrays as
CPU-endian because communication of the mb[] values with the hardware
happens through the readw() and writew() functions. readw() converts from
__le16 to u16 and writew() converts from u16 to __le16. Annotate 'handles'
as CPU-endian because for the firmware these are opaque values.

Casting a pointer to void * and relying on an implicit cast from void *
to uint16_t or uint32_t suppresses sparse warnings about endianness. Hence
cast explicitly to uint16_t and uint32_t. Additionally, remove superfluous

qla2xxx [0001:00:02.0]-e881:1: qla2x00_wait_for_hba_online() failed
The reason of this message is the QLA_FUNCTION_FAILED code that
qla2x00_wait_for_hba_online() returns. However, qlt_disable_vha() expects
that adapter is offlined and QLA_FUNCTION_FAILED informs about the offline
state of the adapter.
The qla2x00_abort_isp() function finishes the execution at the point of
checking the adapter's mode (for example, qla_tgt_mode_enabled()) because
of the qlt_disable_vha() calls qlt_clear_mode() method. It means that
qla2x00_abort_isp() keeps vha->flags.online is equal to zero. Finally,
qla2x00_wait_for_hba_online() checks the state of this flag and returns
QLA_FUNCTION_FAILED error code.
This patch changes the failure message which informs about adapter's
offline state.
