Subject: [PATCH] block: fix issue with calling blk_stop_queue() from the
 request_fn handler

When the queue work handler was converted to delayed work, the
stopping was inadvertently made sync as well. Change this back
to being async stop, using __cancel_delayed_work() instead of
cancel_delayed_work().
