block: don't call blk_mq_quiesce_queue() after queue is frozen
After queue is frozen, no request in this queue can be in use at all, so there can't be any .queue_rq() running on this queue. It isn't necessary to call blk_mq_quiesce_queue() any more, so remove it in both elevator_switch_mq() and blk_mq_update_nr_requests().
