Bluetooth: btusb: Dynamic alternate setting

Browse source 
The alternate setting must be dynamically set according to the number of
active SCO links, and the bit depth of the audio. The possible values
for the alternate setting are described in the Bluetooth Core
Specification, Volume 4, Part B, section 2.1.1.
