Complete the fix of common USB matching options for richcomm_usb

[jimklimov]

Follow-up for #1763: the richcomm_usb.c source does not getval all of the common matching options, and even segfaults during a (failed) matching loop. Debug-traced output of the matching method looks different from that in the other drivers too, so maybe there is obsolete/custom logic in play?

Indeed, a different usb_device_open() (with that custom markup) as well as a less (or differently) sophisticated upsdrv_initups() method are easy to find.
