Fix network info output about compute node

Fix network info output about compute node

In the template version of 2013-05-23, the intrinsic function of
get_attr doesn't support keys or indexes, it requires 2014-10-16 or
higher, the syntax is below:
  get_attr:
    <resource name>
    <attribute name>
    <key/index 1> (optional) not support in 2013-05-23
    <key/index 2> (optional) not support in 2013-05-23

So the translation about compute node's ip address only uses two
parameters currently.
