NFSv4: Reintroduce machine creds
We need to try to ensure that we always use the same credentials whenever we re-establish the clientid on the server. If not, the server won't recognise that we're the same client, and so may not allow us to recover state. Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>
