    sna/gen8: Clear instancing enabled bit between batches

    gen8 sets the instancing bit relative to the vertex element, but we were
    clearing it for the vertex buffer. As the maximum number of vertex
    elements is fixed, just clear them all when emitting our header. Note
    that VF_SGVS is not sufficient by itself to disable all side-effects of
    instancing.

    Thanks to Kenneth Graunke for pointing out the change from vertex buffer
    to vertex element of the instancing enable bit.
