[PATCH mptcp-net 0/2] selftests: mptcp: connect: fix C23 extension warning

["Matthieu Baerts (NGI0)" <matttbe@kernel.org>]

GCC was complaining about the new label:

  mptcp_connect.c:187:2: warning: label followed by a declaration is a C23 extension [-Wc23-extensions]
    187 |         int err = getaddrinfo(node, service, hints, res);
        |         ^

  mptcp_inq.c:79:2: warning: label followed by a declaration is a C23 extension [-Wc23-extensions]
     79 |         int err = getaddrinfo(node, service, hints, res);
        |         ^

  mptcp_sockopt.c:166:2: warning: label followed by a declaration is a C23 extension [-Wc23-extensions]
    166 |         int err = getaddrinfo(node, service, hints, res);
        |         ^

Simply declare 'err' before the label to avoid this warning.
