loopback: Fix transport_generic_allocate_tasks error handling
This patch addresses a tcm_loop bug with transport_generic_allocate_tasks()
return checking in tcm_loop_submission_work() where other non zero return
codes (including -EBUSY for reservation conflicts) are incorrectly falling
through to transport_generic_map_mem_to_cmd() -> transport_handle_cdb_direct().
This bug was introduced into target-pending/for-next-merge with the following
for-3.4 commit:
