staging: comedi: usbduxfast: tidy up usbduxfast_ai_stop()
Remove the devpriv sanity check, all the callers have previously verified that its valid. Absorb usbduxfast_unlink_urbs() into this function since it's the only caller and the only thing it does is call usb_kill_urb(). This function will always succeed so just return 0 and remove the local variable 'ret'.
