When a connection was established without going through NL80211_CMD_CONNECT, the ssid was never set in the wireless_dev struct. Now we set it in __cfg80211_connect_result() when it is not already set. When using a userspace configuration that does not call cfg80211_connect() (can be checked with breakpoints in the kernel), this patch should allow `networkctl status device_name` to output the SSID instead of null.
