drm/i915: Mark all non-vma being inserted into the address spaces
We need to distinguish between full i915_vma structs and simple drm_mm_nodes when considering eviction (i.e. we must be careful not to treat a mere drm_mm_node as a much larger i915_vma causing memory corruption, if we are lucky). To do this, color these not-a-vma with -1 (I915_COLOR_UNEVICTABLE). v2...v200: New name for -1.
