[PATCH] drm/i915: Break after walking all GGTT vma in bump_inactive_ggtt

[PATCH] drm/i915: Break after walking all GGTT vma in bump_inactive_ggtt

[Chris Wilson]

Since commit db6c2b4151f2 ("drm/i915: Store the vma in an rbtree under
the object") the vma are once again sorted into GGTT first, then ppGTT
so that the typical case of walking the GGTT vma can stop as soon as we
find a non-ppGTT. Apply that optimisation.
