target: Fix possible TFO->write_pending() sense_reason_t silent WRITE corruption
This patch fixes a possible case in transport_generic_new_cmd() where a
failure from TFO->write_pending() from a fabric module return something
other than -EAGAIN or -ENOMEM would cause a failed WRITE to silently
succeed.
Go ahead and return TCM_LOGICAL_UNIT_COMMUNICATION_FAILURE for this
special case instead of only just making noise with WARN_ON().
(v2: Fix incorrect exception return for all cases)
