perf: Fix dangling cgroup pointer in cpuctx
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.
Fixes: a3c3c6667("perf/core: Fix child_total_time_enabled accounting bug at task exit")
