Subject: [PATCH 4/6] perf util: Remove unused perf_data__update_dir

From: "Dr. David Alan Gilbert" <linux@...blig.org>

perf_data__update_dir() was added in 2019's
commit e8be135751f2 ("perf data: Add perf_data__update_dir() function")
but has never been used.

Remove it.

Signed-off-by: Dr. David Alan Gilbert <linux@...blig.org>
