The code listing the firmware images inside ModemManager was
attempting to run "DMS Get Stored Image Info" for all PRI images
found, in order to load the Boot version and PRI version reported;
but, turns out the Sierra modems don't support this method, so it was
all failing.

It should be fixed in the following MR:
https://gitlab.freedesktop.org/mobile-broadband/ModemManager/merge_requests/168

Please note that unlike qmicli, which shows all modem and PRI images
separately (and user needs to do the matching), in the case of
ModemManager, only the "correct" combinations will be shown as
possible images to select.
