    vulkan: Set initial layout to undefined
    
    Having the initial layout set to VK_IMAGE_LAYOUT_GENERAL causes issues
    when going from the final layout to the initial layout since the image
    layout is expected to be the general layout. Setting the initial layout
    to undefined doesn't have this restriction.
