drm/i915: Keep vblank interrupts enabled while enabling/disabling planes

Browse source

Because of the upcoming vblank interrupt driven watermark update
mechanism we will have use for vblank interrupts during plane
enabling/disabling. So don't call drm_vblank_off() until planes
are off, and call drm_vblank_on() just before we start to enable
the planes.
