[HAL] Return correct bus handler in HaliFindBusAddressTranslation

This fixes the bug when VidInitialize asks for different translated addresses
    and VgaIsPresent always returns FALSE either because the machine does not have
    VGA controller at all (e.g. 86Duino Zero), or it does have video hardware
    that is not compatible with VGA standard (e.g. Original Xbox).

The problem investigated by Stanislav Motylkov. Suggested fix by Thomas Faber.
