blk-mq: fix regression from commit 624dbe475416
When the code was collapsed to avoid duplication, the recent patch
for ensuring that a queue is idled before free was dropped, which was
added by commit 19c5d84f14d2.
Add back the blk_mq_tag_idle(), to ensure we don't leak a reference
to an active queue when it is freed.
