NFSD: Add support for NFS v4.2 operation checking
The server does allow NFS over v4.2, even if it doesn't add any new
operations yet.
I also switch to using constants to represent the last operation for
each minor version since this makes the code cleaner and easier to
understand at a quick glance.
