    qemu-traditional: disable msitranslate by default
    
    msitranslate is known to cause problems with some device drivers,
    because it sets the real device in MSI mode while making the guest think
    is actually in legacy interrupts mode. Some drivers are able to spot this
    inconsistency and break (Nvidia drivers for example).
    
    Disable the option by default.
