drm/i915: Use i915_vma_offset() in intel_dpt_offset()



Replace the open coded vma mm node stuff in intel_dpt_offset()
with i915_vma_offset(). This will also include the VT-d guard
in the result. Granted that should always be 0 for DPT, but
it seems prudent to include that in our DPT vma offset check
anyway.
