plugin: improve probing decision logic for QMI and MBIM

Browse Source 
So, we may have modems with multiple /dev/cdc-wdm ports, like Ericsson modems,
where only 1 of them is MBIM. With the previous logic, we would probe all
/dev/cdc-wdm ports for MBIM as soon as one of the ports was handled by the
cdc_mbim driver. That is totally not optimal, as we are already know that they
are not MBIM (not handled by cdc_mbim).

Instead, fix the logic to just probe for MBIM or QMI if the actual driver
managing the port is MBIM or QMI.
