    iwlwifi: mvm: BT Coex fix another NULL pointer dereference · 56c07a9c

    This patch is very similar to a previous fix: 22cba0c0
    
    When we disassociate, mac80211 removes the station and
    then, it sets the bss it unsets the assoc bool in bss_info.
    
    Since the firwmware wants it the opposite (first set the
    MAC context as unassoc, and only then, remove the STA of
    the API), we have a small period of time in which the STA
    in firmware doesn't have a valid ieee80211_sta pointer.
    During that time, iwl_mvm_vif->ap_sta_id, is still set
    to the STA in firmware that represent the AP.
