perf data: Close all files in close_dir()

Browse Source 
[ Upstream commit d4b3eedce151e63932ce4a00f1d0baa340a8b907 ]

When using 'perf report' in directory mode, the first file is not closed
on exit, causing a memory leak.

The problem is caused by the iterating variable never reaching 0.

Fixes: 1455206311 ("perf data: Add perf_data__(create_dir|close_dir) functions")
