Ming Lei 9663d294ae block: call rq_qos_exit() after queue is frozen 
[ Upstream commit c57cdf7a9e51d97a43e29b8f4a04157875104000 ]

rq_qos_exit() removes the current q->rq_qos, this action has to be
done after queue is frozen, otherwise the IO queue path may never
be waken up, then IO hang is caused.

So fixes this issue by moving rq_qos_exit() after queue is frozen.
