sched: Reduce some allocation pressure
Since we now allocate SD_LV_MAX * nr_cpu_ids sched_domain/sched_group structures when rebuilding the scheduler toplogy it might make sense to shrink that depending on the CONFIG_ options. This is only needed until we get rid of SD_LV_* alltogether and provide a full dynamic topology interface.
