You're reading the wrong code. In the #ifdef __NetBSD__ portion, it says:

        if ((error = bus_dmamap_load(sc->sc_dmat, sc->sc_ddmamap, sc->sc_desc,
            sc->sc_desc_len, NULL, 0)) != 0) {
                printf("%s: unable to load control data DMA map, error = %d\n",
                    sc->sc_dev.dv_xname, error);
                goto fail3;
        }
