uwb: disable command/event filtering for D-Link DUB-1210

The D-Link DUB-1210 HWA uses commands and events from the WHCI specification,
although reporting itself as WUSB compliant. Therefore, we disable WUSB
command/event filtering for it.

USB_DEVICE_AND_INTERFACE_INFO is used for matching only the RC interface.
