ALSA: msnd: Remove midi code
Nothing calls snd_msndmidi_new()
thus nothing sets chip->msndmidi_mpu
The call to snd_msndmidi_input_read is gated on that being set,
so snd_msndmidi_input_read() won't be called either.
This is probably a missing call to snd_msndmidi_new(), but since
this is ancient code, it's probably best to remove it (especially
since I don't have the hardware to test it).
