sched_ext: Fix rq lock state in hotplug ops
The ops.cpu_online() and ops.cpu_offline() callbacks incorrectly assume
that the rq involved in the operation is locked, which is not the case
during hotplug, triggering the following warning:
WARNING: CPU: 1 PID: 20 at kernel/sched/sched.h:1504 handle_hotplug+0x280/0x340
Fix by not tracking the target rq as locked in the context of
ops.cpu_online() and ops.cpu_offline().
Fixes: 18853ba782bef ("sched_ext: Track currently locked rq")
