tcp_listen_handler() uses the epoll reference for the listening socket it handles, and also passes on one variant of it to tcp_tap_conn_from_sock() and tcp_splice_conn_from_sock(). The latter two functions only need a couple of specific fields from the reference. Pass those specific values instead of the whole reference, which localises the handling of the listening (as opposed to accepted) socket and its reference entirely within tcp_listen_handler().
