sched: only update rq->clock while holding rq->lock
Vatsa noticed rq->clock going funny and tracked it down to an update_rq_clock()
outside a rq->lock section.
This is a problem because things like double_rq_lock() update the rq->clock
value for both rqs. Therefore disabling interrupts isn't strong enough.
