ALSA: usb-audio: Add delay quirk for MOONDROP Moonriver2 Ti

[胡连勤]

Audio control requests that sets sampling frequency sometimes fail on
this card. Adding delay between control messages eliminates that problem.

usb 1-1: New USB device found, idVendor=2fc6, idProduct=f06b
usb 1-1: New USB device strings: Mfr=1, Product=2, SerialNumber=3
usb 1-1: Product: MOONDROP Moonriver2 Ti
usb 1-1: Manufacturer: MOONDROP
usb 1-1: SerialNumber: MOONDROP Moonriver2 Ti
