[PATCH 1/8] sched: Fix hrtick() vs scheduling context

[Peter Zijlstra <peterz@infradead.org>]

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.
