block: Fix race triggered by blk_set_queue_dying()
[ Upstream commit 1b856086813be9371929b6cc62045f9fd470f5a0 ]
blk_set_queue_dying() can be called while another thread is
submitting I/O or changing queue flags, e.g. through dm_stop_queue().
Hence protect the QUEUE_FLAG_DYING flag change with locking.
