Redefine REALTEK_USB_DEVICE for the desired USB interface for probe().
There are three USB interfaces for the device. USB_CLASS_COMM and
USB_CLASS_CDC_DATA are for ECM mode (config #2). USB_CLASS_VENDOR_SPEC
is for the vendor mode (config #1). However, we are not interesting
in USB_CLASS_CDC_DATA for probe(), so redefine REALTEK_USB_DEVICE
to ignore the USB interface class of USB_CLASS_CDC_DATA.
