knfsd: nfsd4: don't delegate files that have had conflicts
One more incremental delegation policy improvement: don't give out a delegation on a file if conflicting access has previously required that a delegation be revoked on that file. (In practice we'll forget about the conflict when the struct nfs4_file is removed on close, so this is of limited use for now, though it should at least solve a temporary problem with self-conflicts on write opens from the same client.)
