perf tools: Fix resources leak in perf_data__open_dir()

[ Upstream commit 0a6564ebd953c4590663c9a3c99a3ea9920ade6f ]

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

Fixes: eb6176709b235b96 ("perf data: Add perf_data__open_dir_data function")
