    usb4bsd: Fix if_urndis/umodem probing conflict.
    Previously, if_urndis would not detect certain devices (among them
    the HTC One) due to a conflict with certain USB modems from Huawei.
    Fix this by making umodem check explicitly for Huawei as the vendor.
    As far as I can see, devd(8) would now load both umodem.ko and
    if_urndis.ko for these modems but only umodem.ko would attach, so
    we should be fine.
    However, so far only the urndis(4) part was actually tested.
