Changed that in git master and qmi-1-10, thanks.

This is not a bug, it's a missing implementation. Listing enabled
locks isn't implemented for QMI modems yet, that's why you see a
"none" there. Not sure if it's just something I forgot to do, or if I
couldn't find correct QMI DMS/UIM messages to query those. Patches
welcome :)
