ondemand put processors at full speed at startup

Hi,

dbs_timer_init() will schedule_work(&dbs_work) so that do_dbs_timer() is likely called very early at same time slice scheduler, and for each cpu, dbs_check_cpu(cpu) will be called, likely at the same time slice than dbs_timer_init().
So far, we will get total_idle_ticks == idle_ticks == 0 unconditonaly, and the processor will be put at full speed even though it's not needed at startup.
