Yu Kuai 4302806dbf block, bfq: protect 'bfqd->queued' by 'bfqd->lock' ...

commit 181490d5321806e537dc5386db5ea640b826bf78 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.
