    u3v: use interface class and subclass in heuristic checks

    don't access the class-specific conversation structure before we know
    that the packet is a U3V packet

    the USB dissector should fill interfaceClass and interfaceSubclass with
    correct values - if it doesn't that's another bug to be fixed
