net: dsa: fix SWITCHDEV_ATTR_ID_BRIDGE_VLAN_FILTERING getting ignored
The bridge emits VLAN filtering events and quite a few others via switchdev with orig_dev = br->dev. After the blamed commit, these events started getting ignored. The point of the patch was to not offload switchdev objects for ports that didn't go through dsa_port_bridge_join, because the configuration is unsupported: - ports that offload a bonding/team interface go through dsa_port_bridge_join when that bonding/team interface is later bridged with another switch port or LAG - ports that don't offload LAG don't get notified of the bridge that is on top of that LAG. Sadly, a check is missing, which is that the orig_dev is equal to the bridge device. This check is compatible with the original intention, because ports that don't offload bridging because they use a software LAG don't have dp->bridge_dev set. On a semi-related note, we should not offload switchdev objects or populate dp->bridge_dev if the driver doesn't implement .port_bridge_join either. However there is no regression associated with that, so it can be done separately.
