Currently, some callers were missing to journal the dirty inode after
adding it to orphan dir.

Now we're going to journal such modifications within the ocfs2_orphan_add()
itself, It's safe to do so, though some existing caller may duplicate this,
and it makes the logic look more straightforward anyway.
