[PATCH net-next 2/6] net: switchdev: move dev in switchdev_fdb_dump

[Vivien Didelot]

The FDB dump callback requires the related net_device so move it to the
struct switchdev_fdb_dump superset instead of using a callback param.

With this done, it'll be simpler to change the dump function signature.
