blk-mq: blk-mq: check quiesce state before queue_rqs
The low level drivers don't expect to see new requests after a
successful quiesce completes. Check the queue quiesce state within the
rcu protected area prior to calling the driver's queue_rqs().
Fixes: 3c67d44de787 ("block: add mq_ops->queue_rqs hook")
