scsi/libiscsi: Fix static checker warning on bh locking

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])",
which we can eliminate by using non bh locking on the nested spin_lock call.
