The cause turns out to be that when the AP station is added but we don't associate, the IWL_STA_UCODE_INPROGRESS is set but never cleared. This then causes iwl_restore_stations() to attempt to resend it because it uses the flag internally and uploads even if it didn't set it itself. To fix this issue and not upload the station again when it has already been removed by mac80211, clear the flag after adding it in case we add it only for association.
