rostests/kmtests/tcpip/TcpIp_user.c: an improper use of ntohs()

TcpIp_user.c

  80     ok_eq_hex(AcceptAddress.sin_port, ntohs(TEST_CONNECT_CLIENT_PORT));

should be either ntohs(sin_port) or htons(TEST_CONNECT_CLIENT_PORT).

NB:
The actual result is identical, yet the code is wrong when reading it.
