NFSv4.1: Don't trust attributes if a pNFS LAYOUTCOMMIT is outstanding
If a LAYOUTCOMMIT is outstanding, then chances are that the metadata server may still be returning incorrect values for the change attribute, ctime, mtime and/or size. Just ignore those attributes for now, and wait for the LAYOUTCOMMIT rpc call to finish.
