3.5.7.4 -stable review patch.  If anyone has any objections, please let me know.

------------------

From: Roland Dreier <roland@purestorage.com>

commit 5a3b6fc0092c5f8dee7820064ee54d2631d48573 upstream.

When transport_lookup_tmr_lun() fails and we return a task management
response from target_complete_tmr_failure(), we need to call
transport_cmd_check_stop_to_fabric() to release the last ref to the
cmd after calling se_tfo->queue_tm_rsp(), or else we will never remove
the failed TMR from the session command list (and we'll end up waiting
forever when trying to tear down the session).

(nab: Fix minor compile breakage)
