    Fix _restore_local_vlan_map race

    Local vlan mappings provisioned by _restore_local_vlan_map
    might not be cleaned up properly if the corresponding ports are
    removed before we enter the main loop.

    This commit fixes the problem by making _restore_local_vlan_map
    just record local vlan IDs and leave the rest of provisioning logic
    to the main loop.
