drm/i915: Pass the plane state explicitly to tracepoints

Using the plane->state pointer in the tracepoints is incorrect
as technically a different state could already have been swapped
in (though in reality that is currently prevented by the stall
hacks in the commit machinery). But let's not leave such footguns
lying around when we can just pass in the correct state by hand.
