[PATCH 7/8] perf bench futex: Clean up two nits in futex hash

[Michal Pluta <michalpl2003@gmail.com>]

The worker's check for an unexpected futex_wait() result tests
'errno != EAGAIN || errno != EWOULDBLOCK', which only works because the
two are equal, so use '&&' instead.

The CPU map is reference counted, so release it with perf_cpu_map__put()
instead of free().
