Allow LUN type disks to have no source

Browse Source 
CD-ROMs and Floppies are allowed to have no source to imply they are
empty or disconnected. Since the LUN type is used for raw CD-ROM access
with QEMU (and VMWare in the future), it also needs to allow an empty
source when the raw CD-ROM device is disconnected from the domain.
