net: dsa: do not open-code dsa_switch_for_each_port
Find the remaining iterators over dst->ports that only filter for the ports belonging to a certain switch, and replace those with the dsa_switch_for_each_port helper that we have now. Signed-off-by: Vladimir Oltean <vladimir.oltean@nxp.com> Signed-off-by: David S. Miller <davem@davemloft.net>
