drm/i915: Use i915_vm_to_ppgtt instead of manual container_of
Looks much better without container_of everywhere. v2: - In i915_gem_restore_gtt_mappings too (Chris) v3: - Do not cause WARN by calling on non PPGTT object (Chris) Cc: Daniel Vetter <daniel.vetter@ffwll.ch> Cc: Chris Wilson <chris@chris-wilson.co.uk> Signed-off-by: Joonas Lahtinen <joonas.lahtinen@linux.intel.com> Reviewed-by: Chris Wilson <chris@chris-wilson.co.uk>
