netfilter: nf_tables: Add notifications for hook changes
Notify user space if netdev hooks are updated due to netdev add/remove
events. Send minimal notification messages by introducing
NFT_MSG_NEWDEV/DELDEV message types describing a single device only.
Upon NETDEV_CHANGENAME, the callback has no information about the
interface's old name. To provide a clear message to user space, include
the hook's stored interface name in the notification.
