perf: duplicate deletion of perf event
a malicious app can open a perf event with constraint_duplicate
bit set, disable the event, and close the fd. On closing the fd,
the perf_release() modification causes the kernel to clean up
the event as if it still were enabled, leading to the event
being removed from a list twice.
