radv: Revert divisor = 0 case for vertex attribute extension.

Seems like DXVK depends on that and it might get reverted
upstream. Since apps are not supposed to use 0 in v2 anyway,
we should be safe implementing the old behavior there.

Fixes: 66e12451ac "radv: Update to new VK_EXT_vertex_attribute_divisor to version 2."
