ALSA: usb-audio: Configure Pioneer DJM-850 samplerate 

Send an `URB_CONTROL out` USB frame to the device to configure its
samplerate. This should be done before using the device for audio
streaming (capture or playback).

See https://github.com/nm2107/Pioneer-DJM-850-driver-reverse-engineering/blob/172fb9a61055960c88c67b7c416fe5bf3609807b/doc/windows-dvs/framerate-setting/README.md
