Tom Yan d8d0db7bb3 ALSA: usb-audio: ignore broken processing/extension unit
Some devices have broken extension unit where getting current value
doesn't work. Attempt that once when creating mixer control for it. If
it fails, just ignore it, so that it won't cripple the device entirely
(and/or make the error floods).
