NFSv4: Remove requirement for machine creds for the "renew" operation
In RFC3530, the RENEW operation is allowed to use either
the same principal, RPC security flavour and (if RPCSEC_GSS), the same
mechanism and service that was used for SETCLIENTID_CONFIRM
OR
Any principal, RPC security flavour and service combination that
currently has an OPEN file on the server.
Choose the latter since that doesn't require us to keep credentials for
the same principal for the entire duration of the mount.
