[ Upstream commit 233f2dc1c284337286f9a64c0152236779a42f6c ]

ASan reports a memory leak related to session->evlist while running:

# perf test "41: Session topology".

When perf_data is in write mode, session->evlist is owned by the caller,
which should also take care of deleting it.

This patch adds the missing evlist__delete().
