drm/i915: Add ww context to intel_dpt_pin, v2.

Browse source

Ensure i915_vma_pin_iomap and vma_unpin are done with dpt->obj lock held.

I don't think there's much of a point in merging intel_dpt_pin() with
intel_pin_fb_obj_dpt(), they touch different objects.

Changes since v1:
- Fix using the wrong pointer to retrieve error code (Julia)
