dm mpath: disable blk_abort_queue
Revert commit 224cb3e981f1b2f9f93dbd49eaef505d17d894c2
dm: Call blk_abort_queue on failed paths
Multipath began to use blk_abort_queue() to allow for
lower latency path deactivation. This was found to
cause list corruption:
the cmd gets blk_abort_queued/timedout run on it and the scsi eh
somehow is able to complete and run scsi_queue_insert while
scsi_request_fn is still trying to process the request.
