cinterion: ignore carrier revision

MV31 MBIM modem firmware revisions are not matched with carrier configs.
Different VoLTE profiles might be selected by the user causing
the carrier config revision to change.

Since fwupd uses this string for firmware updates, it gets confused and
thinks the user has an update available.
