anv: don't advertise mipmaps for linear 3D surfaces on BDW

Browse source 
Prior to SKL, the mipmaps for 3D surfaces are laid out in a way
that make it impossible to represent in the way that
VkSubresourceLayout expects. Since we can't tell users how to make
sense of them, don't report them as available.

"Fixes" dEQP-VK.image.subresource_layout.3d.*
