staging: comedi: usbduxsigma: set *_cmd_running flags before submitting urbs

As pointed out by Ian Abbott, the *_cmd_running flags should be set
before submitting the urbs. There is a possible race condition where
an urb could complete and the flag is checked in the completion
routine before it's set.
