ovpn: properly deconfigure UDP-tunnel

Browse source

When deconfiguring a UDP-tunnel from a socket, we cannot
call setup_udp_tunnel_sock() with an empty config, because
this helper is expected to be invoked only during setup.

Get rid of the call to setup_udp_tunnel_sock() and just
revert what it did during socket initialization..

Note that the global udp_encap_needed_key and the GRO state
are left untouched: udp_destroy_socket() will eventually
take care of them.
