Subject: [PATCH 3.16.y-ckt 136/216] reiserfs: destroy allocated commit workqueue

3.16.7-ckt4 -stable review patch.  If anyone has any objections, please let me know.

------------------

From: Jiri Slaby <jslaby@...e.cz>

commit fa0c5540739320258c3e3a45aaae9dae467b2504 upstream.

When resirefs is trying to mount a partition, it creates a commit
workqueue (sbi->commit_wq). But when mount fails later, the workqueue
is not freed.
