USB: Ignore storage device in modem mode on DWN-652
D-Link DWN-652 in Modem mode exposes 3 interfaces
- First one is the USB storage one
- Second one is for both control and connection
- Third one is unknown
This patch avoids usb-storage trying to switch again when already in
modem mode, and exposes only 2 ttyUSB instead of 3 by not attaching
to the storage interface
