perf c2c: Fix c2c report for empty numa node
Ravi Bangoria reported that we fail with an empty NUMA node with the
following message:
$ lscpu
NUMA node0 CPU(s):
NUMA node1 CPU(s): 0-4
$ sudo ./perf c2c report
node/cpu topology bugFailed setup nodes
Fix this by detecting the empty node and keeping its CPU set empty.
