USB: debugging code shouldn't alter control flow

People have complained that debugging code shouldn't alter the flow of
control; it should restrict itself to printing out warnings and error
messages.  Bowing to popular opinion, this patch (as1518) changes the
debugging checks in usb_submit_urb() to follow this guideline.
