[PATCH] USB: storage: Ignore driver CD interface of SR9700 USB Ethernet adapters

[Ethan Nelson-Moore <enelsonmoore@gmail.com>]

Some SR9700 devices have an SPI flash chip containing a virtual driver
CD, in which case they appear as a device with two interfaces and
product ID 0x9702. Interface 0 is the driver CD and interface 1 is the
Ethernet device. A separate patch to the sr9700 driver will add
support for these devices.
