Wanpeng Li a7bebf4887 sched/deadline: Fix hrtick for a non-leftmost task ...

After update_curr_dl() the current task might not be the leftmost task
anymore. In that case do not start a new hrtick for it.

In this case NEED_RESCHED will be set and the next schedule will start
the hrtick for the new task if and when appropriate.
