net: switchdev: pass callback to dump operation
Similar to the notifier_call callback of a notifier_block, change the
function signature of switchdev dump operation to:
int switchdev_port_obj_dump(struct net_device *dev,
enum switchdev_obj_id id, void *obj,
int (*cb)(void *obj));
This allows the caller to pass and expect back a specific
switchdev_obj_* structure instead of the generic switchdev_obj one.
Drivers implementation of dump operation can now expect this specific
structure and call the callback with it. Drivers have been changed
accordingly.
