[PATCH 08/77] staging: comedi: usbduxsigma: use usbdux_ai_stop() to force unlink all urbs

In tidy_up(), instead of duplicating the code in usbdux_ai_stop() to unlink
all the input urbs, just use usbdux_ai_stop(). Since that function calls
usb_kill_urb() for all the urbs and clears the 'ai_cmd_running' flag, we
can also remove the redundant code in tidy_up().
