ALSA: usb-audio: export snd_usb_feature_unit_ctl
In order to allow quirks functions to hook up to the standard feature unit op tables, this patch exports a pointer to the struct that is used internally. That way, all the code handling the control can be kept private, and external code can reference the symbol to re-use it.
