perf env: Fix sibling_dies memory leak
[ Upstream commit 42db3d9ded555f7148b5695109a7dc8d66f0dde4 ]
ASan reports a memory leak in perf_env while running:
# perf test "41: Session topology"
Caused by sibling_dies not being freed.
This patch adds the required free.
Fixes: acae8b36cded0ee6 ("perf header: Add die information in CPU topology")
