pppoe/disc: drop packets with unsupported PPPoE type

The unsupported-PPPoE-type branch in disc_read() logs a warning but
falls through to forward() instead of dropping the packet. Compare
with the unsupported-version branch immediately above, which has the
same shape but continues:

    if (hdr->ver != 1) {
        if (conf_verbose)
            log_warn(...unsupported version...);
        continue;
    }

    if (hdr->type != 1) {
        if (conf_verbose)
            log_warn(...unsupported type...);
        /* falls through into forward() */
    }

Add the missing continue so malformed packets are dropped instead of
processed.
