nfs41: establish sessions-based clientid
nfsv4.1 clientid is established via EXCHANGE_ID rather than
SETCLIENTID{,_CONFIRM}
This is implemented using a new establish_clid method in
nfs4_state_recovery_ops.
nfs41: establish clientid via exchange id only if cred != NULL
>From 2.6.26 reclaimer() uses machine cred for setting up the client id
therefore it is never expected to be NULL.
