When we want to unwind an error when allocating the PD for gen6, we call gen6_ppgtt_clear_range() telling to clear upto the PD we've previously cleared. However, we passed it the incorrect length, passing it the endpoint instead. Fortunately, as the start was always 0, this has no impact today, but tomorrow we want to start using non-zero origins.
