Subject: loop: return proper error from loop_queue_rq()
From: Omar Sandoval <osandov@xxxxxx>
commit b4a567e8114327518c09f5632339a5954ab975a3 upstream.
->queue_rq() should return one of the BLK_MQ_RQ_QUEUE_* constants, not
an errno.
Fixes: f4aa4c7bbac6 ("block: loop: convert to per-device workqueue")
