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.
