[PATCH 01/47] perf c2c: Display proper cpu count in nodes column

From: Jiri Olsa <jolsa@kernel.org>

There's wrong bitmap considered when checking for cpu count of specific
node.

We do the needed computation for 'set' variable, but at the end we use
the 'c2c_he->cpuset' weight, which shows misleading numbers.
