    x86: provide stub for memory_type_changed
    
    Jan indicated that for PV guests the memory type is not changed, for
    HVM guests memory_type_changed is needed for EPT's effective memory
    type calculation.  This means memory_type_changed is HVM only.
    
    Provide a stub to minimise code churn.
