ALSA: usb-audio: Add QUIRK_FLAG_MIXER_GET_CUR_BROKEN for Logitech PRO X 2 LIGHTSPEED
The UAC mixer of the Logitech PRO X 2 LIGHTSPEED has broken mixer
GET_CUR behavior but otherwise works fine.
Add a quirk table entry matching VID/PID=0x046d/0x0af7 and apply the
MIXER_GET_CUR_BROKEN quirk flag to make the mixer usable again.
Quirky device sample (after applying the quirk flag):
usb 3-2.1: New USB device found, idVendor=046d, idProduct=0af7, bcdDevice= 1.00
usb 3-2.1: New USB device strings: Mfr=1, Product=2, SerialNumber=3
usb 3-2.1: Product: PRO X 2 LIGHTSPEED
usb 3-2.1: Manufacturer: Logitech
usb 3-2.1: SerialNumber: 0000000000000000
usb 3-2.1: 2:0: broken mixer GET_CUR (-18944/0/256 => -2662)
usb 3-2.1: 6:0: broken mixer GET_CUR (-18944/0/256 => 0)
