    sched/hrtick: Fix hrtick() vs. scheduling context

    The sched_class::task_tick() method is called on the donor
    sched_class, and sched_tick() hands it rq->donor as argument,
    which is consistent.

    However, while hrtick() uses the donor sched_class, it then passes
    rq->curr, which is inconsistent. Fix it.
