perf bench futex: Fix memory leak of perf_cpu_map__new()

Browse Source 
[ Upstream commit 88e48238d53682281c9de2a0b65d24d3b64542a0 ]

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: 9c3516d1b8 ("libperf: Add perf_cpu_map__new()/perf_cpu_map__read() functions")
