Namhyung Kim 6f47ed6cd1 perf metric: Do not free metric when failed to resolve 
It's dangerous to free the original metric when it's called from
resolve_metric() as it's already in the metric_list and might have other
resources too.  Instead, it'd better let them bail out and be released
properly at the later stage.

So add a check when it's called from metricgroup__add_metric() and
release it.  Also make sure that mp is set properly.

Fixes: 83de0b7d53 ("perf metric: Collect referenced metrics in struct metric_ref_node")

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.
