qmi_wwan: fix interface number for DW5821e production firmware

The original mapping for the DW5821e was done using a development
version of the firmware. Confirmed with the vendor that the final
USB layout ends up exposing the QMI control/data ports in USB
config #1, interface #0, not in interface #1 (which is now a HID
interface).
