perf c2c: Display proper cpu count in nodes column
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.
Fixes: 1e181b92a2da ("perf c2c report: Add 'node' sort key")
