mds: don't journal opened non-auth inode

If we journal opened non-auth inode, during journal replay, the corresponding
entry will add non-auth objects to the cache. But the MDS does not journal all
subsequent modifications (rmdir,rename) to these non-auth objects, so the code
that manages cache and subtree may get confused. Besides non-auth objects will
be trimmed at the resolve stage.
