Submit #2682: Fix for uaudio driver, so it can be used on DragonFly

Hello. A new uaudio driver for usb4bsd (sys/bus/u4b/audio) needs some care
and love. Currently it can only probe audio devices, that is all. So I
propose a patch which makes this driver useful.

What works: playback with different audio formats and sample rates (8/16
bit pcm, 44.1kHz, 8kHz and so on). Up to 2 channels (what most people need
;). Module loading/unloading.
What does not: multichannel environments, mixer master output level ("vol")
affects only left channel, I really do not know why.
What was not tested: recording

Is it good enough to be committed?

                   With best regards, Vasily.
