perf header: Fix one memory leakage in perf_event__fprintf_event_update()
When dump the raw trace by `perf report -D` ASan reports a memory
leakage in perf_event__fprintf_event_update().
It shows that we allocated a temporary cpumap for dumping the CPUs but
doesn't release it and it's not used elsewhere. Fix this by free the
cpumap after the dumping.
