3.14-stable review patch. If anyone has any objections, please let me know.
------------------
From: Joe Thornber <e...@redhat.com>
commit 7f518ad0a212e2a6fd68630e176af1de395070a7 upstream.
The device details and mapping trees were just being decremented
before. Now btree_del() is called to do a deep delete.
