Replace the hidden getActiveLinkProperties usage

It's a refactor work to remove the hidden connectivity method
usages outside the incoming connectivity module.

CM#getActiveLinkProperties is hidden and no longer supported
outside the module. Caller should replace it with
CM#getLinkProperties(Network), so replace the usage as it is.
