    drm/i915: Only mark as map-and-fenceable when bound into the GGTT

    We use the obj->map_and_fenceable hint for when we already have a
    valid mapping of this object in the aperture. This hint can only apply
    to the GGTT and not to the aliasing-ppGTT. One user of the hint is
    execbuffer relocation, which began to fail when it tried to follow the
    hint and perform the relocate through the non-existent GGTT mapping.
