wifi: cfg80211: Set SSID if it is not already set
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.
