nvme-rdma: unquiesce queues when deleting the controller
If the controller is going away, we need to unquiesce the IO queues so that all pending request can fail gracefully before moving forward with controller deletion. Do that before we destroy the IO queues so blk_cleanup_queue won't block in freeze. Signed-off-by: Sagi Grimberg <sagi@grimberg.me> Signed-off-by: Christoph Hellwig <hch@lst.de>
