perf data: Fix double free in perf_session__delete()

When perf_data__create_dir() fails, it calls close_dir(), but
perf_session__delete() also calls close_dir() and since dir.version and
dir.nr were initialized by perf_data__create_dir(), a double free occurs.

This patch moves the initialization of dir.version and dir.nr after
successful initialization of dir.files, that prevents double freeing.
This behavior is already implemented in perf_data__open_dir().

Fixes: 145520631130bd64 ("perf data: Add perf_data__(create_dir|close_dir) functions")
