net: dsa: b53: skip multicast entries for fdb_dump()
port_fdb_dump() is supposed to only add fdb entries, but we iterate over
the full ARL table, which also includes multicast entries.
So check if the entry is a multicast entry before passing it on to the
callback().
Additionally, the port of those entries is a bitmask, not a port number,
so any included entries would have even be for the wrong port.
Fixes: 1da6df85c6fb ("net: dsa: b53: Implement ARL add/del/dump operations")
