perf bench futex: Fix memory leak of perf_cpu_map__new()
ASan reports memory leaks while running:
$ sudo ./perf bench futex all
The leaks are caused by perf_cpu_map__new not being freed.
This patch adds the missing perf_cpu_map__put since it calls
cpu_map_delete implicitly.
Fixes: 9c3516d1b850ea93 ("libperf: Add perf_cpu_map__new()/perf_cpu_map__read() functions")
