USB: Bugfix for aircable: Add module and name to usb_serial_driver

While adding the dynamic-id support to usb serial I found a small bug in
the air cable driver:

Adds module and name information to the usb_serial_driver instance
of aircable. So the aircable driver is correctly shown under
/sys/bus/usb-serial/drivers/aircable and has the module link.
