perf timechart: Fix max number of cpus
Currently numcpus is determined in pid_put_sample which is only called on sched_switch/sched_wakeup sample processing. On a machine with a lot cpus I often saw the last cpu missing. Check for (max) numcpus on every event happening and in the beginning. -> fixes the issue for me.
