comgt: ncm: try to detect interface for ttyACM ports
Some modems expose ttyACM as their control ports, which have the
"device" symlink pointing one level down in sysfs tree. Try to find
network interfaces for them as well, this is commonly used for modems
exposing ACM + RNDIS or ACM + ECM interface combinations.
