staging: comedi: usbduxsigma: consolidate the firmware upload

Browse source

Absorb the usbduxsub_stop(), usbduxsub_upload(), and usbduxsub_start()
functions into firmwareUpload().

Each of them just do a usb_control_msg() to the device and output
an error message if it fails. A similar message is also output by
firmware_upload() so the extra messages are redundant.

We can also share the malloc'ed local buffer needed for the
usb_control_msg().
