bugfix: Fix duplicate 'address' in standlone SRIOV

* Add unit test per Rodolfo's comment

Creating a VM using generted xml file /tmp/vm_sriov_0.xml returns
an XML error: missing source address type.

This fix modifies generted xml from:
<source>
<address>
<address bus="0x1a" domain="0x0000" function="0x0" slot="0x10" type="pci" />
</address>
</source>

to:

<source>
<address bus="0x1a" domain="0x0000" function="0x0" slot="0x10" type="pci" />
</source>
