Takashi Iwai 7c32ae35fb ALSA: seq: Cover unsubscribe_port() in list_mutex ...

The call of unsubscribe_port() which manages the group count and
module refcount from delete_and_unsubscribe_port() looks racy; it's
not covered by the group list lock, and it's likely a cause of the
reported unbalance at port deletion.  Let's move the call inside the
group list_mutex to plug the hole.
