staging: comedi: usbduxsigma: cleanup the (*cancel) functions
The (*cancel) functions can only be called by the comedi core it the
(*auto_attach) completed successfully. That function sets the comedi_device
'private' variable before initializing the callbacks so the sanity checks
are unnecessary. Remove them.
Also, rename the 'this_usbduxsub' local variable to 'devpriv' as this is
more common in comedi drivers.
Remove the unnecessary comments.
