Takashi Iwai cc9dbfa970 ALSA: usb-audio: Fix incorrect NULL check in create_yamaha_midi_quirk() ...

The commit 60849562a5 ("ALSA: usb-audio: Fix possible NULL
dereference at create_yamaha_midi_quirk()") added NULL checks in
create_yamaha_midi_quirk(), but there was an overlook.  The code
allows one of either injd or outjd is NULL, but the second if check
made returning -ENODEV if any of them is NULL.  Fix it in a proper
form.
