Are you missing assinging the pinfo to the port with
snd_seq_set_port_info() ? I think the correct sequence should be this one:

  snd_seq_get_port_info(seq, port, pinfo);

  snd_seq_port_info_set_timestamping(pinfo, 1);
  snd_seq_port_info_set_timestamp_queue(pinfo, queue);
  snd_seq_port_info_set_timestamp_real(pinfo, 1);

  snd_seq_set_port_info(seq, port, pinfo);
