When connectivity is lost to a device, the association is terminated and the blk-mq queues are quiesced/stopped. When connectivity is re-established, they are resumed. If connectivity is lost for a sufficient amount of time that the controller is then deleted, the delete path starts tearing down queues, and eventually calling nvme_ns_remove(). It appears that pending commands may cause blk_cleanup_queue() to never complete and the teardown stalls. Correct by starting the ns queues after transitioning to a DELETING state, allowing pending commands to be flushed with io failures. Thus the delete path is clear when reached.
