When a connexion was established without going through NL80211_CMD_CONNECT, the ssid was never set in the wireless_dev struct. Now we set it during when an NL80211_CMD_AUTHENTICATE is issued.

It may be needed to test this on some additional hardware (tested with iwlwifi and a AX201, and iwd on the userspace side), I could not test things like roaming and p2p.

This applies to v6.2-rc7, but I think it may also be interesting to backport it from 5.19 to 6.1
