Routine Description:

    System dispatch function for handling IRP_MJ_SYSTEM_CONTROL IRPs from WMI.

Arguments:

    pDeviceObject   - Pointer to device object. The device extension field
                      contains a pointer to the Interface 

    pIrp            - Pointer to IRP.

Return Value:

    NT status code.
