vyos.ifconfig: T4330: bugfix changing MTU when IPv6 is disabled
Commit f8b3d8999c ("ipv6: T4319: do not configure IPv6 related settings if it's disabled") moved the MTU configuration part under the code path which is only run if IPv6 is enabled on the system. This prevented MTU changes on IPv6 disabled systems.
