Commit 659743b [SCSI] libiscsi: Reduce locking contention in fast path
introduced a
new smatch warning on libiscsi.c iscsi_xmit_task() warn: inconsistent returns
bottom_half:: locked (1410 [(-61)]) unlocked (1425 [0], 1425
[s32min-(-1),1-s32max]),
The format strings for various printk()s make use of a temporary
variable that is declared 'static'. This is probably not intended,
so fix those.

Simply the I/O completion logic by folding scsi_end_request into its only
caller. There is a single site to either requeue the command or move on
to the next one instead of of the previous convoluted logic.

The host lock is a serious scalability problem on 2-socket and larger
systems which are doing a lot of I/O. Before removing the temporary
