nfsd41: stateid handling
When sessions are used, stateful operation sequenceid and stateid handling
are not used. When sessions are used, on the first open set the seqid to 1,
mark state confirmed and skip seqid processing.
When sessionas are used the stateid generation number is ignored when it is zero
whereas without sessions bad_stateid or stale stateid is returned.
Add flags to propagate session use to all stateful ops and down to
check_stateid_generation.
