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.
