Commit 39a2bd34c933 ("drm/i915: Use the vma resource as argument for gtt
binding / unbinding") introduced a regression that due to the vma resource
tracking of the binding state, dpt ptes were not correctly repopulated.
Fix this by clearing the vma resource state before repopulating.
The state will subsequently be restored by the bind_vma operation.
