ALSA: rawmidi: Move lock to snd_rawmidi_substream
Having a lock in snd_rawmidi_runtime can be a problem especially when
a substream is accessed from the outside, as the runtime creation
might be racy with the external calls. As a first step for hardening,
move the spinlock from snd_rawmidi_runtime to snd_rawmidi_substream.
This patch just replaces the lock calls, no real functional change is
put yet.
