Yu Kuai 6ffad92d05 blk-cgroup: fix missing put device in error path from blkg_conf_pref() 
[ Upstream commit 15c30104965101b8e76b24d27035569d6613a7d6 ]

If blk_queue_enter() failed due to queue is dying, the
blkdev_put_no_open() is needed because blkcg_conf_open_bdev() succeeded.

Fixes: 0c9d338c8443 ("blk-cgroup: synchronize blkg creation against policy deactivation")
