Close socket so that it doesn't leak

In file services/listen_dnsport.c the function create_local_accept_sock seems to leak resource s (socket) whereas in function create_tcp_accept_sock that doesn't happen.

Please find attached a proposed diff, for your revision, to close the socket whenever an error is found.

Hi Ricardo,

Thank you for the find and the fix.  I note that this routine is only called at startup, so the leak would not have accumulated.  The patch is great, and I have integrated it into the code repository.

Best regards, Wouter
