MLK-22653-2 drm/imx: dpu: crtc: Do not send out bogus vblank event in ->atomic_disable()

When a full modeset is needed, the CRTC could be totally disabled or
enabled/re-enabled after the modeset.  If it's re-enabled, a vblank
event would be sent during the CRTC enablement procedure.  So, a bogus
event should be killed in the ->atomic_disable() callback.
