Routine Description:

    HidP_FreePreparsedData to free the memory allocated to this structure when
    it is no longer needed.

Arguments:
   HidDeviceObject A handle to a Hid Device that the client obtains using 
                   a call to CreateFile on a valid Hid device string name.
                   The string name can be obtained using standard PnP calls.
