tcp: Register fds with epoll at flow creation

Register connection sockets with epoll using empty events
(events=0) in tcp_conn_from_tap(), tcp_tap_conn_from_sock()
and tcp_flow_repair_socket().

This allows tcp_epoll_ctl() to always use EPOLL_CTL_MOD, removing
the need to check whether fds are already registered. As a result, the
conditional ADD/MOD logic is no longer needed, simplifying the function.
