drm/i915: Ensure state->crtc is non-NULL for plane updates
When disabling a plane, it is legal to pass crtc = NULL. Since planes
on Intel hardware are tied to a fixed CRTC, go ahead and set state->crtc
to the appropriate crtc in cases where it is passed to us as NULL.
In a future patch, we will start using the update handler for plane
disables, so this will help ensure we always have a non-NULL crtc
pointer to work with.
