Passing an argument of the latter kind twice without clearing it in between is wrong: if the first call sets an error, it no longer points to NULL for the second call. machine_parse_property_opt() is wrong that way: it passes @errp to keyval_parse() without checking for failure, then passes it to keyval_merge(). Harmless, since the only caller passes &error_fatal. Clean up: drop the parameter, and use &error_fatal directly.
