hurd: Fix FS_RETRY_MAGICAL "machtype" handling
We need to set file_name, not update retryname. This is what the other branches do. Before this change, any attempt to access such a file would segfault due to file_name being unset: $ settrans -ac /tmp/my-machtype /hurd/magic machtype $ cat /tmp/my-machtype Segmentation fault Checked on i686-gnu.
