vbo: fix incorrect min/max_index values in display list draw call

vbo: fix incorrect min/max_index values in display list draw call

This fixes another regression from commit 8e4efdc895ea ("vbo: optimize
some display list drawing").  The problem was the min_index, max_index
values passed to the vbo drawing function were not computed to compensate
for the biased prim::start values.
