ocfs2: fix possible memory leak in ocfs2_finish_quota_recovery
[ Upstream commit cdc3ed3035d0fe934aa1d9b78ce256752fd3bb7d ]
If ocfs2_finish_quota_recovery() exits due to an error before passing all
rc_list elements to ocfs2_recover_local_quota_file() then it can lead to a
memory leak as rc_list may still contain elements that have to be freed.
Release all memory allocated by ocfs2_add_recovery_chunk() using
ocfs2_free_quota_recovery() instead of kfree().
