staging: ath6kl: cfg80211_roam issue; driver wedge

If a heavy traffic is undergoing and a link is lost (bcn miss),
wlan driver does a reconnection on its own and after connection
is re-established, reports it as ROAM_EVENT to cfg. Now this event
is handled as work queue. It could very well happen that by the
time this event gets handled, cfg would have aged out the bss and
we get the following WARN_ON in __cfg80211_roamed function in file
net/wireless/sme.c.

        /* internal error -- how did we get to CONNECTED w/o BSS? */
        if (WARN_ON(!wdev->current_bss)) {
                return;
        }
To resolve the issue we report the BSS whenever we send a connect or
roam event to the cfg.
