sna/present: Remove stale assert that fake vblanks only have one event

    sna/present: Requeue early vblank completions

we may hit the fake vblank timer path with an old hw struct that may have
multiple associated events. The assert that we only called the fake
vblank from sna_present_queue_vblank is no longer correct.
