        sys/dev/audio/audio.c: revision 1.60
        sys/dev/audio/audio.c: revision 1.62

Fix wrong parameter displayed in debug messages.

Restore backward compatibility with netbsd-7 audio.

For sticky parameters (encoding, precision, channels, sample_rate and pause):
 - AUDIO_SETINFO for nonexistent track updates sticky parameters.
 - AUDIO_GETINFO for nonexistent track reads sticky parameters.

For blocksize, hiwat, lowat and {play.record}.buffer_size:
 - AUDIO_SETINFO for nonexistent track does nothing.
 - AUDIO_GETINFO for nonexistent track returns dummy non-zero values.

Nonexistent track is a playback track on O_RDONLY descriptor for example,
or both tracks on /dev/audioctl.
