John Ernberg 4152b387da USB: option: fix Cinterion AHxx enumeration 
In certain kernel configurations where the cdc_ether and option drivers
are compiled as modules there can occur a race condition in enumeration.
This causes the option driver to enumerate the ethernet(wwan) interface
as usb-serial interfaces.

usb-devices output for the modem:
