[Mesa-dev] [PATCH] draw: fix a regression in computing max elt

[Zack Rusin]

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.
