stm32: usb: register control handlers in config callback

Browse Source 
As found in 6f2b39c1be6a8b9531264d92138dc2629d51cfa0, you can't just register a
control callback by itself, you can only register them in the set config
callback, (or, at least, _after_ set config has been done.

This has been compile tested only for the extra examples that were found to
have this failing pattern.
