mesa/st: Prevent 'end' < 'start' in vbo_exec_DrawRangeElementsBaseVertex()

We adjust 'end' to fit into _MaxElement, but that may result into a 'start'
value bigger than 'end' being passed downstream, causing havoc.

This could be seen with arb_robustness_draw-vbo-bounds, due to an
application bug.
