nfs41: sequence operation

Browse source 
Implement the sequence operation conforming to
http://tools.ietf.org/html/draft-ietf-nfsv4-minorversion1-26

Check returned sessionid, slotid and slot sequenceid in decode_sequence.

If the server returns different values for sessionID, slotID or slot sequence
number than what was sent, the server is looney tunes.

Pass the sequence operation status to nfs41_sequence_done in order to
determine when to increment the slot sequence ID.

Free slot is separated from sequence done.
