perf: Fix cgroup state vs ERROR

While chasing down a missing perf_cgroup_event_disable() elsewhere,
Leo Yan found that both perf_put_aux_event() and
perf_remove_sibling_event() were also missing one.

Specifically, the rule is that events that switch to OFF,ERROR need to
call perf_cgroup_event_disable().

Unify the disable paths to ensure this.

Fixes: 9f0c4fa1 ("perf/core: Add a new PERF_EV_CAP_SIBLING event capability")
