Subject: [PATCH] staging: comedi: usbdux: tidy up usbdux_ai_cancel()

Rename the local variable used for the private data pointer to the
comedi "norm".

Remove the unnecessary sanity check of the private data pointer. This
function can only be called is the private data was allocated during
the attach.
