Johan Hovold 51cb8e206a ALSA: usb-audio: fix control-request direction ...

The direction of the pipe argument must match the request-type direction
bit or control requests may fail depending on the host-controller-driver
implementation.

Fix the UAC2_CS_CUR request which erroneously used usb_sndctrlpipe().
