drm/i915/vrr: Don't send push for legacy cursor updates

We don't really want legacy cursor updates to trigger
VRR pushes because these can happen willy nilly and we
generally want more precise control over the pushes.
The fastpath in intel_legacy_cursor_update() doesn't
send pushes, but if we punt to the full commit path
(with the flip completion short circuited) we are currently
sending pushes. Skip those as well so that they don't
interfere with the push handling from normal commits.
