Eric Dumazet b58662a5f7 tcp: ulp: fix possible crash in tcp_diag_get_aux_size() 
tcp_diag_get_aux_size() can be called with sockets in any state.

icsk_ulp_ops is only present for full sockets.

For SYN_RECV or TIME_WAIT ones we would access garbage.

Fixes: 61723b393292 ("tcp: ulp: add functions to dump ulp-specific information")
