[PATCH] optimize activate_task()

recalc_task_prio() is called from activate_task() to calculate dynamic
priority and interactive credit for the activating task.  For real-time
scheduling process, all that dynamic calculation is thrown away at the end
because rt priority is fixed.  Patch to optimize recalc_task_prio() away
for rt processes.
