Subject: [PATCH] Reduce stale management VLAN entries on config save

The firmware has a single management VLAN (one management_vlan variable),
so a stored config should never carry more than one "vlan N mgmt" line.
When parsing a mgmt command, drop any previously stored mgmt entry so
repeatedly changing the management VLAN no longer accumulates stale lines.
