From: Sagi Grimberg <sagi@xxxxxxxxxxx> [ Upstream commit 90140624e8face94207003ac9a9d2a329b309d68 ] 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.
