drm: Apply tight eviction scanning to color_adjust
Using mm->color_adjust makes the eviction scanner much tricker since we don't know the actual neighbours of the target hole until after it is created (after scanning is complete). To work out whether we need to evict the neighbours because they impact upon the hole, we have to then check the hole afterwards - requiring an extra step in the user of the eviction scanner when they apply color_adjust. v2: Massage kerneldoc.
