[ Upstream commit 65bff0be9b154621b617fc2e4bd89f1e18e97cdb ]
Do address translations only between shared links. It is possible that while an non-AP MLD station and an AP MLD station have shared links, the frame is intended to be sent on a link which is not shared (for example when sending a probe response).
