If the patch is merged, it should be upgraded to loop through all the
VMA's in GGTT, not only the ones that present whole objects.

Just a matter of adding looping in place of the obj_to_ggtt call.

Also, the i915_gem_object_is_inactive seems to be there as a leftover
added function, never gets called.
