net: dsa: sja1105: hide all multicast addresses from "bridge fdb show"

Browse source 
Commit 4d94235495 ("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.

Fixes: 291d1e72b7 ("net: dsa: sja1105: Add support for FDB and MDB management")
