st/nine: Don't update unused world matrices
While to the application we have to track
accurately all 256 world matrices (including
in stateblocks), hw vertex processing enables
to set a limit to the number of world matrices
the hardware can access to in the advertised caps,
which is 8 for nine.
Thus don't bother in the stateblock code to send
the updated values for the unreachable matrices.
