selftests: mptcp: connect: fix maybe-uninitialize warn

This warning can be seen with GCC 15.2:

  mptcp_connect.c: In function ‘main_loop’:
  mptcp_connect.c:1422:37: warning: ‘peer’ may be used uninitialized [-Wmaybe-uninitialized]
   1422 |                 if (connect(fd, peer->ai_addr, peer->ai_addrlen))
        |                                 ~~~~^~~~~~~~~
  mptcp_connect.c:1377:26: note: ‘peer’ was declared here
   1377 |         struct addrinfo *peer;
        |                          ^~~~

This variable is set in sock_connect_mptcp() in some conditions. If not,
this helper returns an error, and the program stops. So this is a false
positive, but better removing it by initialising peer to NULL.
