sched: reorder update_cpu_load(rq) with the ->task_tick() call
Peter Williams suggested to flip the order of update_cpu_load(rq) with the ->task_tick() call. This is a NOP for the current scheduler (the two functions are independent of each other), ->task_tick() might create some state for update_cpu_load() in the future (or in PlugSched).
