perf kmem: Make it work again on non NUMA machines
The commit '2814eb0 perf kmem: Remove die() calls' disabled 'perf kmem' command for machines without numa support. It made the command fail if '/sys/devices/system/node' dir wasn't found. Skipping the numa based initialization in case the directory is not found and continue execution.
