broadband-modem-qmi,broadband-modem-mbim: always use SMS_PART_INVALID_INDEX unstored parts

MMSmsList has logic to allow multiple unstored messages as long as
they use SMS_PART_INVALID_INDEX. These messages aren't stored so
they don't have an index.

But the MBIM and QMI modems used index 0 for unstored messages,
meaning there could only ever be one and also that multipart
messages would fail to be combined.

Let's fix that by just using SMS_PART_INVALID_INDEX for every
scenario where an unstored message comes in.
