port-mbim: before attempting to use QMI over MBIM, check device services

If we blindly try to use QMI over MBIM on devices that don't support it, the logic works ok but it's very slow, given that the QMI device open operation has several internal retries, and all those end up timing out.

Avoid that lost time by checking the list of services supported by the MBIM modem, and if the QMI over MBIM service is not listed, we'll avoid trying to open the QMI device right away.
