Fixed DHCP issue

Correct device name for OpenSUSE 13.1 / VMware is _ens33_

To get rid of this, see http://www.freedesktop.org/wiki/Software/systemd/PredictableNetworkInterfaceNames/

```

link '/etc/udev/rules.d/80-net-name-slot.rules' do
  to '/dev/null'
  only_if do
    node.platform == 'opensuse' && node.platform_version == '13.1'
  end
end

```
