Subject: [PATCH] staging: comedi: usbduxsigma: use usbdux_pwm_stop() to force
 unlink urb

In tidy_up(), instead of duplicating the code in usbdux_pwm_stop() to
unlink the pwm urb, just use usbdux_pwm_stop(). Since that function calls
usb_kill_urb() and clears the 'pwm_cmd_running' flag, we can also remove
the redundant code in tidy_up().
