sound: usb-audio: add workaround for Blue Microphones devices
commit 8886f33f25083a47d5fa24ad7b57bb708c5c5403 upstream.
Blue Microphones USB devices have an alternate setting that sends two
channels of data to the computer. Unfortunately, the descriptors of
that altsetting have a wrong channel setting, which means that any
recorded data from such a device has twice the sample rate from what
would be expected.
This patch adds a workaround to ignore that altsetting. Since these
devices have only one actual channel, no data is lost.
