sched: Wrap scheduler p->cpus_allowed access
This task is preparatory for the migrate_disable() implementation, but stands on its own and provides a cleanup. It currently only converts those sites required for task-placement. Kosaki-san once mentioned replacing cpus_allowed with a proper cpumask_t instead of the NR_CPUS sized array it currently is, that would also require something like this.
