mctp: serial: enforce fixed MTU
The current serial driver requires a maximum MTU of 68, and it doesn't make sense to set a MTU below the MCTP-required baseline (of 68) either. This change sets the min_mtu & max_mtu of the mctp netdev, essentially disallowing changes. By using these instead of a ndo_change_mtu op, we get the netlink extacks reported too.
