NFSv4: Add recovery for individual stateids
NFSv4 defines a number of state errors which the client does not currently handle. Among those we should worry about are: NFS4ERR_ADMIN_REVOKED - the server's administrator revoked our locks and/or delegations. NFS4ERR_BAD_STATEID - the client and server are out of sync, possibly due to a delegation return racing with an OPEN request. NFS4ERR_OPENMODE - the client attempted to do something not sanctioned by the open mode of the stateid. Should normally just occur as a result of a delegation return race.
