Subject: [PATCH net-next v2] net: switchdev: switchdev_handle_fdb_del_to_device(): fix no-op function for disabled CONFIG_NET_SWITCHDEV

In patch 8ca07176ab00 ("net: switchdev: introduce a fanout helper for
SWITCHDEV_FDB_{ADD,DEL}_TO_DEVICE") new functionality including static
inline no-op functions if CONFIG_NET_SWITCHDEV is disabled was added.

This patch fixes the following build error for disabled
CONFIG_NET_SWITCHDEV:
