ALSA: rawmidi: Drop register_mutex in snd_rawmidi_free()
commit a70aef7982b012e86dfd39fbb235e76a21ae778a upstream.
The register_mutex taken around the dev_unregister callback call in
snd_rawmidi_free() may potentially lead to a mutex deadlock, when OSS
emulation and a hot unplug are involved.
Since the mutex doesn't protect the actual race (as the registration
itself is already protected by another means), let's drop it.
