    [XBOXVMP] Fix in VideoPortGetAccessRanges call: missing Slot parameter.
    
    Contrary to what is (badly) written on MSDN, this parameter is
    *mandatory* when the ranges looked for are on a PCI adapter.
    
    Detected when testing with MS Windows' videoprt.sys on XBOX emulator;
    thanks to Simone Lombardo for assistance!
