staging: comedi: usbduxsigma: use usbdux_ao_stop() to force unlink all urbs

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