sched, rt: Convert switched_{from, to}_rt() / prio_changed_rt() to balance callbacks

Browse source

Remove the direct {push,pull} balancing operations from
switched_{from,to}_rt() / prio_changed_rt() and use the balance
callback queue.

Again, err on the side of too many reschedules; since too few is a
hard bug while too many is just annoying.
