If the disk type is "block", and the source drive is a CD-ROM, the
virtual tray state should be tied to the physical tray, even though this
isn't always the case due to QEMU bugs.

Perhaps you should fail creation if the tray attribute is "open" in the
above circumstances.  Another possibility is to forbid specifying the
tray attribute completely.

Or you can just drop this patch, and only print the tray state in the
virsh dumpxml output.  There are other attributes that already handled
this way.
