Subject: [PATCH 03/20] perf test: session_topology: delete session->evlist

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