sched: Fix select_task_rq() vs hotplug issues

commit 5da9a0fb673a0ea0a093862f95f6b89b3390c31e upstream

Since select_task_rq() is now responsible for guaranteeing
->cpus_allowed and cpu_active_mask, we need to verify this.

select_task_rq_rt() can blindly return
smp_processor_id()/task_cpu() without checking the valid masks,
select_task_rq_fair() can do the same in the rare case that all
SD_flags are disabled.
