[PATCH] nfsd: nfsd: remove pg_authenticate field

The pg_authenticate (now pg_authenticate_obsolete) callback was only being
used by the nfs4 client callback code to circumvent the svcauth_unix code's
insistence on checking all requests against the export table.  With that
problem solved, we no longer need it.
