tcfm_dev always points to the correct netdev and we already hold a refcnt, so no need to use tcfm_ifindex to lookup again. If we would support moving target netdev across netns, using pointer would be better than ifindex. This also fixes dumping obsolete ifindex, now after the target device is gone we just dump 0 as ifindex.
