We still need to unquiesce queue for avoiding hanging blk_freeze_queue()
in blk_cleanup_queue() since any new request queued during quiescing
can't be dispatched to driver/device.
Yes, already added it in v2.
There are other blk_mq_tagset_busy_iter() in mtip_service_thread(),
which looks need quiesce too.
Wasn't sure about those two... I agree it looks like quiescing is
needed, will add in v2.
This case is even worse, because both
mtip_abort_cmd() and mtip_queue_cmd() do not check if the req is
started.
Its easy enough to add.
