[libvirt] Fix qemudParseVMDeviceDef() to check for proper network device tag name

[Kaitlin Rupert]

Is it too late to get this change in?

Instead of "net", the tag name should be "interface".  Previously, 
attempting to attach a network device to a KVM guest would return:

libvir: QEMU error : XML description for unknown device type is not well 
formed or invalid
error: Failed to attach device from attach-disk.xml

With this fix, it returns:

libvir: QEMU error test_domain: this function is not supported by the 
hypervisor: only CDROM disk devices can be attached
libvir: QEMU error : this function is not supported by the hypervisor: 
only CDROM disk devices can be attached
error: Failed to attach device from attach-disk.xml
