FS#1304 - DDNS does not function with QMI protocol and IP does not appear in LuCI
User who did this - Jo-Philipp Wich (jow-)

----------
The QMI protocol handler will spawn a virtual sub-interface "wwan_4" which handles the actual IPv4 connectivity. Instruct the DDNS subsystem to pull its IP from there.
