freedreno/a6xx: fix array pitch for layer-first layouts

Fixes:
 gl-3.2-layered-rendering-gl-layer-render
 gl-3.2-layered-rendering-gl-layer-render-clipped
 gl-3.2-layered-rendering-gl-layer-render-storage
 gl-3.2-layered-rendering-gl-layer-cube-map

Would fix:
 amd_vertex_shader_layer-layered-2d-texture-render
when GL_AMD_vertex_shader_layer is enabled.

Closes: #3929
