geneve: fix fill_info when using collect_metadata
Since 9b4437a5b870 ("geneve: Unify LWT and netdev handling.") fill_info does not return UDP_ZERO_CSUM6_RX when using COLLECT_METADATA. This is because it uses ip_tunnel_info_af() with the device level info, which is not valid for COLLECT_METADATA. Fix by checking for the presence of the actual sockets. Fixes: 9b4437a5b870 ("geneve: Unify LWT and netdev handling.") Signed-off-by: Eric Garver <e@erig.me> Acked-by: Pravin B Shelar <pshelar@ovn.org> Signed-off-by: David S. Miller <davem@davemloft.net>
