plugin-manager: handle race condition during probing
The specific case:
* Modem exposes cdc-wdm port, Generic plugin probes it successfully as QMI.
* Modem exposes new ports, including the wwan one. All ttys fail probing
because they're neither AT nor QCDM (CnS in this case).
* The wwan port ends up without a port being suggested and is not grabbed.
The root cause of this is that we do not propagate the suggested plugin to newly
added ports when it's the Generic one. If it wasn't the Generic one, the newly
added ports would start with the suggested one for probing.
Now, handle this by looking for the device-specified plugin when the port
probing ends without a specific port given. If there is such a device-specified
plugin accept the port, and otherwise, reject it.
