domain_descriptor: correctly check if element is present

As per Python ETree documentation:

Caution: Elements with no subelements will test as False. This
behavior will change in future versions. Use specific len(elem) or
elem is None test instead.

This caused the expression to evaluate to None instead of VM's memory,
overwriting the VM's conf with invalid value.
