anv: Clamp depth buffer dimensions to be at least 1.
When there are no framebuffer attachments, fb->width and fb->height will
be 0. Subtracting 1 results in 4294967295 which is too large for the
field, causing genxml assertions when trying to create the packet.
In this case, we can just program it to 1.
