Now that interface 3 in "option" driver is no longer mapped, add device
ID matching it to qmi_wwan.

The modem is used inside ZTE MF283+ router and carriers identify it as
such.
Interface mapping is:
0: QCDM, 1: AT (PCUI), 2: AT (Modem), 3: QMI, 4: ADB

I see that the usb-serial counterpart of this patch was queued up for 
stable [1], so just for the sake of completeness, it might be worthy to 
consider this one too. This would likely make OpenWrt folks happy -  I 
think that going for 5.4.y and upper would suffice, as 5.4 is currently 
used as stable kernel there, and most of targets are switching to 5.10 
right now.

Upstream commit is 88eee9b7b42e69fb622ddb3ff6f37e8e4347f5b2.
