net: dcb: application priority is per net_device
The app_data priority may not be the same for all net devices.
In order for stacks with application notifiers to identify the
specific net device dcb_app_type should be passed in the ptr.
This allows handlers to use dev_get_by_name() to pin priority
to net devices.
