From: Dave Airlie <airl...@redhat.com>
We have some cases where in subpass we want the layer but having
it be 0 and loaded in the frag shader without the vertex shader
exporting it is fine.
So don't export the layer if we don't have a value to put in it.
Fixes: d4c74aed7a8 (radv/multiview: mark layer_input if we have input
attachments.)
