ALSA: seq: Deletion of unnecessary checks before the function call "snd_midi_event_free"

Browse source 
The snd_midi_event_free() function tests whether its argument is NULL and then
returns immediately. Thus the test around the call is not needed.

This issue was detected by using the Coccinelle software.
