Yeoreum Yun ae1ada0af1 perf: Fix dangling cgroup pointer in cpuctx ...

[ Upstream commit 3b7a34aebb ]

Commit a3c3c6667("perf/core: Fix child_total_time_enabled accounting
bug at task exit") moves the event->state update to before
list_del_event(). This makes the event->state test in list_del_event()
always false; never calling perf_cgroup_event_disable().

As a result, cpuctx->cgrp won't be cleared properly; causing havoc.
