Vladimir Oltean 1699b4d502 net: dsa: fix NULL pointer dereference in dsa_port_reset_vlan_filtering 
The "ds" iterator variable used in dsa_port_reset_vlan_filtering() ->
dsa_switch_for_each_port() overwrites the "dp" received as argument,
which is later used to call dsa_port_vlan_filtering() proper.

As a result, switches which do enter that code path (the ones with
vlan_filtering_is_global=true) will dereference an invalid dp in
dsa_port_reset_vlan_filtering() after leaving a VLAN-aware bridge.

Use a dedicated "other_dp" iterator variable to avoid this from
happening.

Fixes: d0004a020bb5 ("net: dsa: remove the "dsa_to_port in a loop" antipattern from the core")
