sched/psi: Avoid updating PSI triggers and ->rtpoll_total when there are no state changes
When psimon wakes up and there are no state changes for ->rtpoll_states,
it's unnecessary to update triggers and ->rtpoll_total because the pressures
being monitored by the user have not changed.
This will help to slightly reduce unnecessary computations of PSI.
