[RFC] netdev: destroy auth-proto in connect event, for ext auth

[James Prestwood <prestwoj@gmail.com>]

With external auth there is no associate event meaning the auth proto
never gets freed, which prevents eapol from starting inside the
OCI callback. Check for this specific case and free the auth proto
in the connect event.
