[PATCH v3] drm/i915: Object w/o backing stroage is banned by -ENXIO

[Tina Zhang]

-ENXIO should be returned when operations are banned from changing
backing storage of objects without backing storage.

v3:
- Separate this patch from "Introduce GEM proxy" patch-set. (Joonas)

v2:
- update the patch description and subject to just mention objects w/o
  backing storage, instead of "GEM proxy". (Joonas)
