[ Upstream commit fc56f54f6fcd5337634f4545af6459613129b432 ]

ASan reports a memory leak when running:

  # perf test "49: Synthesize attr update"

Caused by evlist not being deleted.

This patch adds the missing evlist__delete and removes the
perf_cpu_map__put since it's already being deleted by evlist__delete.
