This is allowed by the specification, as the following VUIDs state:
VUID-vkCmdResolveImage-srcImage-04446
If dstImage is of type VK_IMAGE_TYPE_3D, then for each element of
pRegions, srcSubresource.layerCount must be 1
VUID-vkCmdResolveImage-srcImage-04447
If dstImage is of type VK_IMAGE_TYPE_3D, then for each element of
pRegions, dstSubresource.baseArrayLayer must be 0 and
dstSubresource.layerCount must be 1
New tests coming for it: dEQP-VK.pipeline.*.multisample.3d.*
