3.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Wang Shilong <wangsl.f...@cn.fujitsu.com>
commit 90515e7f5d7d24cbb2a4038a3f1b5cfa2921aa17 upstream.
We may return early in btrfs_drop_snapshot(), we shouldn't
call btrfs_std_err() for this case, fix it.
