[ Upstream commit 02c652f5465011126152bbd93b6a582a1d0c32f1 ]

Commit 4d9423549501 ("net: dsa: sja1105: offload bridge port flags to
device") has partially hidden some multicast entries from showing up in
the "bridge fdb show" output, but it wasn't enough. Addresses which are
added through "bridge mdb add" still show up. Hide them all.
