i965/draw: Stop relying on min_index == -1 for invalid index bounds
The vbo layer passes an index_bounds_valid flag that we should be using
instead. This also fixes a bug when min_index == -1 and basevertex != 0
where we were actually comparing min_index + basevertex == -1 which was
false and we were getting the wrong buffer-sizing path.
