[PATCH net 7/8] selftests: mptcp: connect: fix C23 extension warning

[Matthieu Baerts (NGI0)]

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);
        |         ^

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

Fixes: a862771d1aa4 ("selftests: mptcp: use IPPROTO_MPTCP for getaddrinfo")
