wifi: mac80211_hwsim: Fix MLD address translation
[ 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).
