Complain if srpt_abort_cmd() is called for an I/O context that is
being processed by SCST and not by the HCA.

Only complain about a missing completion for I/O contexts that are
in a state where the ib_srpt driver is waiting for the HCA.

Apparently with mlx4 firmware up to and including 2.30.8000 it is not
guaranteed that for a QP associated with an SRQ error completions are
generated for all pending work requests. Avoid triggering
srpt_pending_cmd_timeout() for missing error completions.

Invoking srpt_zerolength_write() before the queue pair has reached
the error state is a bug, so complain loudly if that happens.

The overhead of atomic_add_return() is lower than that of a
spin_lock() / spin_unlock() pair, hence switch to the former.

All callers guarantee that the completion queue is empty so it is
not necessary to invoke ib_poll_cq() from inside this function.

After having changed the queue pair state into "error", queue an additional
work request instead of waiting for the last WQE event.

This is necessary to avoid that a login gets rejected due to reusing a
queue pair number that has not yet been freed by the target side.

Store initiator and target port ID's once per nexus instead of in each
channel data structure.

Although harmless for SCSI commands with SIMPLE ordering, avoid that commands
received before RTU can get reordered.

The mlx4_core driver generates a GID change event after a port has been
changed from IB into Ethernet mode. Avoid that this causes the following
error message to appear in the system log:
ib_srpt: ***ERROR***: received unrecognized IB event 18

All ioctx->state manipulations are serialized per command so it is
not necessary to use locking to protect these manipulations.

Some components don't have 'uninstall' targets although the top-level
Makefile references them. Some others don't remove the proper file.

Not all SCST components handle DESTDIR properly, or at all.
In particular:
* INSTALL_MOD_PATH should account for DESTDIR when 'make modules_install'
is invoked, so the kernel make infrastructure deploys the modules
and runs depmod against the proper directory tree.
* depmods must include a '-b' option to reference the proper directory tree.
* Drop special ISCSI_DESTDIR.

When deriving the kernel version (KVER) from KDIR, the file
$(KDIR)/include/config/kernel.release should be preferred over
'make kernelversion'.
For example, the Ubuntu 3.2.0-23-generic kernel has a kernel.release
file containing '3.2.0-23-generic', but 'make kernelversion' returns
3.2.14. Since the modules are stored under /lib/modules/3.2.0-23-generic,
the value in kernel.release is the correct one to use.
Also:
- Evaluate KVER only once
- All depmod commands must include KVER

Avoid that disabling a target triggers a race condition with
SRP relogin. At least in theory this race condition could result
in a kernel crash.
