u_blitter: add support for saving vertex buffers

Currently r300g does not save vertex buffer on blitter calls.

It gets away with it because the current Mesa state tracker usually
resets vertex buffers on every draw calls.

However, this is wrong.

nvfx won't be lucky because it needs to use the blitter inside draw
calls.

Just set the max index to 1, this lets doom3 run and seems correct,
