[PATCH 5/7] drm/i915/gem/ttm: Respect the objection region in placement_from_obj

[Jason Ekstrand]

Whenever we had a user object (n_placements > 0), we were ignoring
obj->mm.region and always putting obj->placements[0] as the requested
region.  For LMEM+SMEM objects, this was causing them to get shoved into
LMEM on every i915_ttm_get_pages() even when SMEM was requested by, say,
i915_gem_object_migrate().
