before this check, the nodeid has already been checked once, so
the check here doesn't make an sense, so remove the check for
nodeid here.

            if (err || !outarg->nodeid)
                    goto out_put_forget;

            err = -EIO;
    >>>     if (!outarg->nodeid)
                    goto out_put_forget;
