net: Make NETDEV_XXX commands enum { }
This patch is preparation to drop NETDEV_UNREGISTER_FINAL. Since the cmd is used in usnic_ib_netdev_event_to_string() to get cmd name, after plain removing NETDEV_UNREGISTER_FINAL from everywhere, we'd have holes in event2str[] in this function. Instead of that, let's make NETDEV_XXX commands names available for everyone, and to define netdev_cmd_to_name() in the way we won't have to shaffle names after their numbers are changed.
