[Ocfs2-devel] [PATCH 2/2] ocfs2: do not call brelse() if group_bh is not initialized in ocfs2_group_add()

[Younger Liu <younger.liu@huawei.com>]

If group_bh is not initialized, there is no need to release.
This problem does not cause anything wrong, but the patch 
would make the code more logical.
