Yu Kuai 4302806dbf block, bfq: protect 'bfqd->queued' by 'bfqd->lock' ... commit 181490d532 upstream. If bfq_schedule_dispatch() is called from bfq_idle_slice_timer_body(), then 'bfqd->queued' is read without holding 'bfqd->lock'. This is wrong since it can be wrote concurrently. Fix the problem by holding 'bfqd->lock' in such case.
