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

From: Riccardo Mancini <hidden>
Date: 2021-07-15 16:07:40

Subsystem: performance events subsystem, the rest · Maintainers: Peter Zijlstra, Ingo Molnar, Arnaldo Carvalho de Melo, Namhyung Kim, Linus Torvalds

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.
