[ Upstream commit 8730c1ddb6 ]
When tearing down a controller the following warning is issued:
WARNING: CPU: 0 PID: 30681 at ../kernel/workqueue.c:2418 check_flush_dependency
This happens as the err_work workqueue item is scheduled on the
system workqueue (which has WQ_MEM_RECLAIM not set), but is flushed
from a workqueue which has WQ_MEM_RECLAIM set.
Fix this by providing an FC-NVMe specific workqueue.
Fixes: 4cff280a5f ("nvme-fc: resolve io failures during connect")
