[ Upstream commit 49985bc466b51af88d534485631c8cd8c9c65f43 ]

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
