Subject: [net-next V2 15/17] net/mlx5: Bridge, extract FDB delete notification to function

From: Vlad Buslov <vladbu@...dia.com>

SWITCHDEV_FDB_DEL_TO_BRIDGE notification is generated in multiple places in
bridge code. Following patch in series changes the condition for the
notification. Extract the notification into dedicated helper function
mlx5_esw_bridge_fdb_del_notify() to only modify it in single place in the
future changes.
