[Bridge] [PATCH net-next 4/6] net: bridge: add __br_mdb_do
br_mdb_add and br_mdb_del call respectively __br_mdb_add and __br_mdb_del and notify the message type on success. Factorize this in a new __br_mdb_do function which add or delete a br_mdb_entry depending on the message type, then notify it. Note that the dev argument is p->br->dev, so no need to pass it twice.
