net: dsa: b53: fix VLAN ID for untagged vlan on bridge leave

Browse Source 
[ Upstream commit a1c1901c5cc881425cc45992ab6c5418174e9e5a ]

The untagged default VLAN is added to the default vlan, which may be
one, but we modify the VLAN 0 entry on bridge leave.

Fix this to use the correct VLAN entry for the default pvid.
