Sohaib Mohamed 99643bdc6f perf bench futex: Fix memory leak of perf_cpu_map__new() 
[ Upstream commit 88e48238d5 ]

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")

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
