It is possible for a target driver to pass a scatterlist via
scst_cmd_set_tgt_sg() that is valid for the vdisk_fileio handler
but not for the vdisk_blockio handler. Complain loudly if an invalid
scatterlist is passed to vdisk_blockio because such scatterlists
cause silent data corruption with most Linux block drivers.

This change makes integration with OpenStack easier since OpenStack GUIDs
are 36 characters long: 32 hex characters and four dashes.

scst_vdisk: Remove a superfluous cast
The 'iov_base' member of 'struct iovec' is declared in
<uapi/linux/uio.h> with type 'void __user *'. Adding an integer
to a void pointer has the same effect as adding an integer to
a char pointer in the C language. This means that it is safe to
remove the cast in front of the eiv->iov_base pointer.
Please note that a similar construct already exists in the iSCSI
target driver. From the nthread.c source file:
iop->iov_base += rest;
iop->iov_len -= rest;
This patch does not change any functionality.

scst_vdisk: Reduce number of casts
Since 'address' points at kernel space memory, change its type
from uint8_t __user * into uint8_t *. This change reduces the
number of casts between uint8_t __user * to uint8_t * in
fileio_exec_write().
This patch does not change any functionality.

scst_vdisk, MODE SELECT(10): Interpret both bytes of the BLOCK DESCRIPTOR LENGTH field
While the BLOCK DESCRIPTOR LENGTH field spans a single byte in the
Mode parameter header(6), the size of this field in the Mode parameter
header(10) is two bytes. Interpret both bytes while executing a MODE
SELECT(10) command.

scst, iscsi-scst: Add thread_pid attribute
For SCST devices with a short name determining which SCST command
threads serve a given LUN requires an (expensive) walk of the
process table. For SCST devices with a long name it is not possible
to determine unambiguously which command threads serve a given
LUN. Hence add a thread_pid sysfs attribute that makes it easy to
figure out which command threads serve a LUN.
