    i965: re-emit index buffer state on a reset option change.

    Seems like we forget to update the index buffer (ib) status and
    IndexedDrawCutIndexEnable or CutIndexEnable flag is left unchanged it
    leads to ignoring of glEnable/glDisable functions for GL_PRIMITIVE_RESTART
    in some cases. The index buffer (ib) status should be re-emmited after the
    reset option change to avoid some unexpected behavior.
