The only TLV that we don't pass to List Messages is the one specifying
which message tags you want to query (e.g. I want only
QMI_WMS_MESSAGE_TAG_TYPE_MT_READ). When that TLV is not set, the modem
should return all messages. Maybe the modem really wants that TLV, and
if so, we would need to loop querying for all 4 known tags for each
message store.
