selftests: mptcp: sockopt: fix C23 extension warning

Browse Source 
commit 3259889fd3c0cc165b7e9ee375c789875dd32326 upstream.

GCC was complaining about the new label:

  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.
