mptcp: Avoid NULL dereference in mptcp_getsockopt_subflow_addrs()
Coverity complains of a possible NULL dereference in
mptcp_getsockopt_subflow_addrs():
861 } else if (sk->sk_family == AF_INET6) {
3. returned_null: inet6_sk returns NULL. [show details]
4. var_assigned: Assigning: np = NULL return value from inet6_sk.
862 const struct ipv6_pinfo *np = inet6_sk(sk);
Fix this by checking for NULL.
Closes: https://github.com/multipath-tcp/mptcp_net-next/issues/231
Fixes: c11c5906bc0a ("mptcp: add MPTCP_SUBFLOW_ADDRS getsockopt support")
