According to the comments and logging, the author just hope user to use
the core and device which are in the same numa node for optimal
performance. If not, A warning gives out.

For example in flow_classify:
./build/flow_classify -a 0000:7d:00.1  -l 93
0000:7d:00.1 is on numa node 0.
core 93  is on numa node 3.

The two are not in same numa node, but no warning gives out in old codes.

This patch can fix it.
