[PATCH netifd 2/2] bridge: bridge_dump_info: add dumping of bridge attributes

[Petr Štetiar]

There are internal decisions being made using several bridge attributes
like for example in bridge_reload(), but those attributes are not
available for the outside inspection, thus hard to follow.

So lets make inspection easier and simply just add dumping of those
bridge attributes as well.
