Since f12fa9ee6c (userdiff: add and use for_each_userdiff_driver(), 2021-04-08), lookup of userdiffs is done with a generic for_each_userdiff_driver(). But the name lookup doesn't use the "type" field, of course. We can't get rid of that field from the generic interface because it is used by t/helper/test-userdiff.c. So mark it as unused in this instance to silence -Wunused-parameter.
