cfg80211: fix potential connection work crash
If wpa_supplicant and iw/iwconfig are used together, very rarely the system crashes. It seems to be related to the connection parameters not being set up, but it's not all clear to me how this happens. In any case, checking that the conn pointer exists here is probably a good idea.
