perf bench: Fix failing assertions in numa bench
Patch adds more subtle handling of -C and -N parameters in parse_{cpu,node}_setup_list() functions when there isn't enough NUMA nodes or CPUs present. Instead of assertion and terminating benchmark, partial test is skipped with error message and perf will continue to the next one. Fixed problem can be easily reproduced on machine with only one NUMA node: # Running numa/mem benchmark... # Running main, "perf bench numa mem -a" ... # Running RAM-bw-remote, "perf bench numa mem -p 1 -t 1 -P 1024 -C 0 -M 1 -s perf: bench/numa.c:622: parse_setup_node_list: Assertion `!(bind_node_0 < 0 || bind_node_0 >= g->p.nr_nodes)' failed.
