In the NFSv4.1 case, the client callback server knows that the connection is valid, 'cos we're the ones who set it up. All we care about is to make sure the session is still valid. If it isn't, then NFS4ERR_BADSESSION is the correct reply. NFSv4.0 is an altogether different kettle of fish since we need to authenticate the connection too.
