Variable cfg_val is being assigned but is never used hence it is
redundant and can be removed.

Cleans up clang warning:
warning: variable 'cfg_val' set but not used [-Wunused-but-set-variable]

[ Background info about val_bit field from alsa-devel ML thread:
 tiwai: Actually this made me wonder what is the definition of val_bit.
	It seems always 1 in the current code after the commit
	964ca808. Pierre?
 pbossart: This val_bit is only there for debug/test, it should be set
	to one by default and has nothing to do with the lpcm_id.
	This variable was set even in patches before upstream
	submission and was never needed, I guess it must be a 9-yr
	old issue. Good catch!

The sequencer core module doesn't call some destructors in the error
path of the init code, which may leave some resources.

This patch mainly fix these leaks by calling the destructors
appropriately at alsa_seq_init().  Also the patch brings a few
cleanups along with it, namely:

- Expand the old "if ((err = xxx) < 0)" coding style
- Get rid of empty seq_queue_init() and its caller
- Change snd_seq_info_done() to void

Last but not least, a couple of functions lose __exit annotation since
they are called also in alsa_seq_init().

No functional changes but minor code cleanups.

snd_midi_event_encode_byte() can never fail, and it can return rather
true/false.  Change the return type to bool, adjust the argument to
receive a MIDI byte as unsigned char, and adjust the comment
accordingly.  This allows callers to drop error checks, which
simplifies the code.

Meanwhile, snd_midi_event_encode() helper is used only in seq_midi.c,
and it can be better folded into it.  This will reduce the total
amount of lines in the end.

Make use of UAC3 Power Domains associated to an Audio Streaming
path within the PCM's logic. This means, when there is no audio
being transferred (pcm is closed), the host will set the Power Domain
associated to that substream to state D1. When audio is being transferred
(from hw_params onwards), the Power Domain will be set to D0 state.

This is the way the host lets the device know which Terminal
is going to be actively used and it is for the device to
manage its own internal resources on that UAC3 Power Domain.

Note the resume method now sets the Power Domain to D1 state as
resuming the device doesn't mean audio streaming will occur.

Set the UAC3 Power Domain state for an Audio Streaming interface
to D2 state before suspending the device (usb_driver callback).
This lets the device know there is no intention to use any of the
Units in the Audio Function and that the host is not going to
even listen for wake-up events (interrupts) on the units.

When the usb_driver gets resumed, the state D0 (fully powered) will
be set. This ties up the UAC3 Power Domains to the runtime PM.
