[BUGFIX][PATCH v6 2/9] perf config: If collect_config() is failed, finally free a config set after it is done

Show all headers | View raw

Because of die() at perf_parse_file() a config set was freed
in collect_config(), if failed.
But it is natural to free a config set after collect_config() is done
when some problems happened.

So, in case of failure, lastly free a config set at perf_config_set__new()
instead of freeing the config set in collect_config().
