ALSA: seq: remove useless function

Browse Source 
The function snd_seq_queue_client_termination() is only called from
the function seq_free_client1(). The function seq_free_client1() calls
the function snd_seq_queue_client_leave() and the function
snd_seq_queue_client_termination() together. Because the function
snd_seq_queue_client_leave() does all things, so the function
snd_seq_queue_client_termination() is a useless function.
