tipc udp_bearer does not need to access struct socket itself in the fast path; it only reads struct sock, and struct socket is only used for tunnel setup and teardown. Let's store struct sock directly in struct udp_bearer. Note that cleanup_bearer() calls synchronize_net() after udp_tunnel_sock_release(), so udp_bearer is not freed until inflight fast paths finish. Note also that synchronize_rcu() is added in the error path of tipc_udp_enable() since udp_bearer will be kfree()d immediately once we remove synchronize_rcu() in udp_tunnel_sock_release(). This can be later converted to kfree_rcu().
