Chris Wilson 6239901c57 drm/i915/gtt: Use NULL to encode scratch shadow entries 
We can simplify our gtt walking code by comparing against NULL for
scratch entries as opposed to looking up the distinct per-level scratch
pointer.

The only caveat is to remember to protect external parties and map the
NULL to the scratch top pd.
