imap-send: mark unused parameter in ssl_socket_connect() fallback

Commit cea1ff7 (imap-send: drop global `imap_server_conf` variable,
2024-06-07) added an imap_server_conf parameter to several functions.
But when compiled with NO_OPENSSL, the ssl_socket_connect() fallback
just returns immediately, so its parameters all need to be annotated to
avoid triggering -Wunused-parameter.
