In ocfs2_remove_btree_range, when calling ocfs2_lock_refcount_tree and
ocfs2_prepare_refcount_change_for_del failed, it goes to out and then
tries to call mutex_unlock without mutex_lock before.

It's better to merge both into one patch because it's apparent that
ocfs2_reserve_blocks_for_rec_trunc() need to fix in the same way for
