Satheesh Rajendran 8b6c6ab154 perf bench numa: Fixup discontiguous/sparse numa nodes ...

[ Upstream commit 321a7c35c9 ]

Certain systems are designed to have sparse/discontiguous nodes.  On
such systems, 'perf bench numa' hangs, shows wrong number of nodes and
shows values for non-existent nodes. Handle this by only taking nodes
that are exposed by kernel to userspace.
