It looks like some systems have quite a few devices that report -1 as 
numa_node value causing lots of warning messages being printed.
Quick fixes that come to mind would be:
1) Change log level to DEBUG
2) Add static var to only print the message once.

I also think that the message itself should show at least the BDF to at 
least know which devices are reporting bad numa_node values.

Thoughts?

Sergio
