Subject: [PATCH] nm: don't clear connection DNS if global DNS is not specified
If the global DNS state is not specified, let's not overwrite it in
Networkmanager profiles while doing unrelated changes.
This is consistent with mainline (Rust) version of nmstate.
Resolves: https://issues.redhat.com/browse/RHEL-31095
