How frequently is srat_resolve_its_pxm called?

The SRAT has affinity entries for each memory segment, CPU and ITS block. Comes upto ~260 entries on my ThunderX2. We go into the main logic of srat_resolve_its_pxm() only for ITS blocks (2 entries).

I took a second look at this, and ran some more testing. I need to fix up a bug and add more comments.

Will update this diff.

Fix the check for warning (i > 1 now), fix up error message, and add a comment.
