The function snd_seq_queue_client_termination() is only called from function seq_free_client1(). The seq_free_client1() calls function snd_seq_queue_client_leave(), which deletes all objects whose owner equals to client->number in global array queue_list, before the function snd_seq_queue_client_termination(), which checks whether there are any objects in global array queue_list whose owner equals to client->number, with the same argument client->number. So the checking code in function snd_seq_queue_client_termination() is dead code. Remove those dead code.
