gnrc_tcp_open() previously would eventually fail with a timeout without sending any data when no netif was specified and a link-local target address was used. This fixes the behavior: - If there is only one netif, we just pick that - If there are multiple netifs, fail directly with `-EINVAL` rather than sending out nothing and waiting for a timeout.
