nbd: fix nbd device deletion
commit 8364da4751cf22201d74933d5e634176f44ed407 upstream.
This fixes a use after free bug, we shouldn't be doing disk->queue right
after we do del_gendisk(disk). Save the queue and do the cleanup after
the del_gendisk.
Fixes: c6a4759ea0c9 ("nbd: add device refcounting")
