nfsd: don't assume copy notify when preprocessing the stateid
Move the stateid handling to nfsd4_copy_notify.
If nfs4_preprocess_stateid_op did not produce an output stateid, error out.
Copy notify specifically does not permit the use of special stateids,
so enforce that outside generic stateid pre-processing.
