usb: gadget zero style fixups (mostly whitespace) 



Minor updates to "Gadget Zero".

 - Primarily these are whitespace updates to address the fact that since
   this was written, Documentation/CodingStyle was changed to disapprove
   of parts of the original coding style.

 - Update a few comments that weren't quite correct, notably mentioning
   the "autoresume" module parameter.
