Fix divide by zero in radeon_surface

Passing a tile_split of zero to eg_surface_init_2d causes a divide by zero
error. Launching chromium with WebGL enabled on a AMD Llano (A8-3850) exhibits
this behavior and webgl then fails to work. The attached patch fixes the
problem and allows WebGL to work in chrome on this platform.
