[Intel-gfx] [PATCH 4/5] drm/i915: Pass old crtc state to intel_crtc_vblank_off()

[Ville Syrjala]

From: Ville Syrjälä <ville.syrjala at linux.intel.com>

To make life easier in the future let's pass the old crtc state
to intel_crtc_vblank_off() just like we already do for its
counterpart intel_crtc_vblank_on().
