net: Teach pegasus driver to ignore bluetoother adapters with clashing Vendor:Product IDs

The Belkin F8T012xx1 bluetooth adaptor has the same vendor and product
IDs as the Belkin F5D5050, so we need to teach the pegasus driver to
ignore adaptors belonging to the "Wireless" class 0xE0. For this one
case anyway, seeing as pegasus is a driver for "Wired" adaptors.
