[PATCH 04/20] perf test: event_update: fix memory leak of evlist

From: Riccardo Mancini
Date: Thu Jul 15 2021 - 12:07:40 EST


ASan reports a memory leak when running the 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.
