[ Upstream commit 4db2a5ef4ccbe6d138828284cfab241b434b5d95 ]
The blamed refactoring commit changed a "port" iterator with "other_dp",
but still looked at the slave_dev of the dp outside the loop, instead of
other_dp->slave from the loop.
As a result, dsa_port_vlan_filtering() would not call
dsa_slave_manage_vlan_filtering() except for the port in cause, and not
for all switch ports as expected.
Fixes: d0004a020bb5 ("net: dsa: remove the "dsa_to_port in a loop" antipattern from the core")
