ALSA: Clean up snd_device_*() codes
A few code cleanups and optimizations. In addition, drop
snd_device_disconnect() that isn't used at all, and drop the return
values from snd_device_free*().
Another slight difference by this change is that now the device state
will become always SNDRV_DEV_REGISTERED no matter whether dev_register
ops is present or not. It's for better consistency. There should be
no impact for the current tree, as the state isn't checked.
