bus: ignore scan and probe failures

Browse Source 
Bus scan is responsible for finding devices over *all* buses.
Some of these buses might not be able to scan but that should
not prevent other buses to be scanned.

Same is the case for probing. It is possible that some devices which
were scanned didn't have a specific driver. That should not prevent
other buses from being probed.
