Currently the XML parser already allows the following syntax:
<disk type='block' device='cdrom'>
<source startupPolicy='optional'/>
<target dev='hda' bus='ide'/>
<address type='drive' controller='0' bus='0' target='0' unit='0'/>
</disk>
But it did not support writing out the <source> entry without the actual
dev value. It would print dev='(null)'. This change allows it to write
out XML to match the parser.
