Namhyung Kim 43d9473e7c perf evlist: Fix cpu/thread map leak
[ Upstream commit bfd1b83d75e44a9f65de30accb3dd3b5940bd3ac ]

Asan reported leak of cpu and thread maps as they have one more refcount
than released.  I found that after setting evlist maps it should release
it's refcount.

It seems to be broken from the beginning so I chose the original commit
as the culprit.  But not sure how it's applied to stable trees since
there are many changes in the code after that.

Fixes: 7e2ed09753 ("perf evlist: Store pointer to the cpu and thread maps")
Fixes: 4112eb1899 ("perf evlist: Default to syswide target when no thread/cpu maps set")

README

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.
