Return a QDict with the following device information:

- "domain": domain number
- "bus": bus number
- "slot": slot number
- "function": function number

This commit should not change user output, the following is an
example of the returned QDict:

{ "domain": 0, "bus": 0, "slot": 5, "function": 0 }

Please, note that this is only in case of success. In error
conditions the handler still calls monitor_printf() directly,
as errors are not being converted yet.
