[PATCH] tools/perf/tests: Remove duplicate evlist__delete in tests/tool_pmu.c

[PATCH] tools/perf/tests: Remove duplicate evlist__delete in tests/tool_pmu.c

[Athira Rajeev]

The testcase for tool_pmu failed in powerpc as below:

 ./perf test -v "Parsing without PMU name"
  8: Tool PMU                                                        :
  8.1: Parsing without PMU name                                      : FAILED!

This happens when parse_events results in either skip or fail
of an event. Because the code invokes evlist__delete(evlist)
and "goto out".

	ret = parse_events(evlist, str, &err);
	if (ret) {
		 evlist__delete(evlist);

But in the "out" section also evlist__delete happens.

	out:
        evlist__delete(evlist);
        return ret;

Hence remove the duplicate evlist__delete from the first path
in the testcase

With the change:
	# ./perf test -v "Parsing without PMU name"
	  8: Tool PMU                                                        :
	  8.1: Parsing without PMU name                                      : Ok
