I just fixed this in "drivers/block/rbd.c" and I noticed that
"drivers/block/nbd.c" has the same problem. Fix a warning
issued by sparse by adding some lockdep annotations
to indicate the queue lock gets dropped (because it's
held when do_nbd_request() is called) and re-acquired
within the function.
