sched: let sched_boost take precedence over sched_restrict_cluster_spill
When sched_restrict_cluster_spill knob is enabled, RT tasks are restricted
to lower power cluster. This knob also restricts inter cluster no-hz kicks.
Ignore this knob setting when sched_boost is enabled so that tasks are
placed on CPUs with highest spare capacity.
