st/scroll-view: Don't queue redraw in update_fade_effect()

ClutterEffects are responsible for queueing redraws when their
properties change (and StScrollViewFade is a good citizen already), also
Clutter itself should queue a redraw when adding/removing an effect.

Users of Clutter should never have to queue redraws themselves (unless
they're implementing a custom ClutterEffect or ClutterContent), so don't
queue a redraw here.
