blk-mq: move _blk_mq_update_nr_hw_queues synchronize_rcu call

This fixes the
4.14 backport commit 574eb136ec7f315c3ef2ca68fa9b3e16c56baa24
which was
upstream commit f5bbbbe4d63577026f908a809f22f5fd5a90ea1f.

The upstream commit added a call to synchronize_rcu to
_blk_mq_update_nr_hw_queues, just after freezing queues.

In the backport this landed just after unfreezeing queues.

This commit moves the call to its intended place.

Fixes: 574eb136ec7f ("blk-mq: sync the update nr_hw_queues with blk_mq_queue_tag_busy_iter")
