drm/i915: Fix display problems after resume
commit 6c482c6 upstream. Commit 39a2bd3 ("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.
