dccp: Call inet6_destroy_sock() via sk->sk_destruct().
commit 1651951ebea54970e0bda60c638fc2eee7a6218f upstream. After commit d38afeec26ed ("tcp/udp: Call inet6_destroy_sock() in IPv6 sk->sk_destruct()."), we call inet6_destroy_sock() in sk->sk_destruct() by setting inet6_sock_destruct() to it to make sure we do not leak inet6-specific resources. DCCP sets its own sk->sk_destruct() in the dccp_init_sock(), and DCCPv6 socket shares it by calling the same init function via dccp_v6_init_sock(). To call inet6_sock_destruct() from DCCPv6 sk->sk_destruct(), we export it and set dccp_v6_sk_destruct() in the init function.
