r300_cmdbuf: Always emit INDX_BUFFER immediately after DRAW_INDEX
DRAW_INDEX writes a vertex count to VAP_VF_CNTL. Docs say that behaviour is undefined (i.e. lockups happen) when this write is not followed by the right number of vertex indices. Thus we used to do the wrong thing when drawing across many cliprects was necessary, because we emitted a sequence DRAW_INDEX, DRAW_INDEX, INDX_BUFFER, INDX_BUFFER instead of DRAW_INDEX, INDX_BUFFER, DRAW_INDEX, INDX_BUFFER The latter is what we're doing now and which ought to be correct.
