nfsd4: only require krb5 principal for NFSv4.0 callbacks
In the sessions backchannel case, we don't need a krb5 principal name for the client; we use the already-created forechannel credentials instead. Some cleanup, while we're there: make it clearer which code here is 4.0- or sessions- specific. Signed-off-by: J. Bruce Fields <bfields@redhat.com>
