nfsd41: sequence operation
Implement the sequence operation conforming to
http://tools.ietf.org/html/draft-ietf-nfsv4-minorversion1-26
Check for stale clientid (as derived from the sessionid).
Enforce slotid range and exactly-once semantics using
the slotid and seqid.
If everything went well renew the client lease and
mark the slot INPROGRESS.
Add a struct nfsd4_slot pointer to struct nfsd4_compound_state.
To be used for sessions DRC replay.
