node: don't set write-only NodeAddressingElement.AddressType property
node: don't set write-only NodeAddressingElement.AddressType property

This field is only ever set but never read (i.e. inside the CNI). We
need to keep the property as part of the API because of backwards
compatibility, but it's fine to no longer set it.

This allows to drop pkg/node.getNodeIP and fold it into
pkg/node.GetNodeIP.
