draw: fix a regression in computing max elt
gl can use elts without setting indices, in which case our eltMax was set to 0 and always invoking the overflow condition. So by default set eltMax to maximum, it will be curbed by draw_set_indexes (if it ever comes) and if not then it will let gl's glVertexPointer/glDrawArrays work correctly. Fixes piglit's triangle-rasterization-overdraw test. Signed-off-by: Zack Rusin <[email protected]> Reviewed-by: Jose Fonseca <[email protected]>
