Fix the race between checking for contexts on the runqueue and actually waking them in spu_deactive and spu_yield. The guts of spu_reschedule are split into a new helper called grab_runnable_context which shows if there is a runnable thread below a specified priority and if yes removes if from the runqueue and uses it. This function is used by the new __spu_deactivate hepler shared by preemption and spu_yield to grab a new context before deactivating a specified priority and if yes removes if from the runqueue and uses it. This function is used by the new __spu_deactivate hepler shared by preemption and spu_yield to grab a new context before deactivating the old one.
