You have successfully blacklisted the interface in the cdc_ether drvier,
but you also need to add it to the qmi_wwan driver to complete the move
from one driver to another.  Use the entry for the Novatel E362 as a
template.

The only purpose of this is to make qmi-based tools work with the modem,
*if* they do so...  I don't think that is confirmed yet for this device
ID, which is different from the E371 variants we've seen before.
