base-modem: plug leaks when organizing ports

Aleksander Morgado requested to merge aleksm/ModemManager:aleksander/fix-lists-leaks into master

The GLists maintained in the logic need to be explicitly freed (just the lists, not the list contents) if we exit early on error or if we end up deciding that the specific ports are available but unsupported by the plugin (e.g. if a plugin that doesn't support net ports finds net ports in the modem).
