perf tools: Fix resources leak in perf_data__open_dir

[PATCH] perf tools: Fix resources leak in perf_data__open_dir

Posted by Miaoqian Lin 2 years, 8 months ago

In perf_data__open_dir(), opendir() opens the directory stream.
Add missing closedir() to release it after use.

Fixes: eb6176709b23 ("perf data: Add perf_data__open_dir_data function")
