From: Ilan Peer <[email protected]> The minimum chandef bandwidth calculation was done only in case a new station was inserted (or when an existing station was removed). However, it is possible that stations are inserted before they are associated, e.g., when FULL_AP_CLIENT_STATE is supported and user space adds stations unassociated.
Fix this by calling ieee80211_recalc_min_chandef() whenever a station transitions in/out the associated state, and only consider station marked as associated.
