vlan: use a valid default mtu value for vlan over macsec
macsec can't cope with mtu frames which need vlan tag insertion, and vlan device set the default mtu equal to the underlying dev's one. By default vlan over macsec devices use invalid mtu, dropping all the large packets. This patch adds a netif helper to check if an upper vlan device needs mtu reduction. The helper is used during vlan devices initialization to set a valid default and during mtu updating to forbid invalid, too bit, mtu values. The helper currently only check if the lower dev is a macsec device, if we get more users, we need to update only the helper (possibly reserving an additional IFF bit).
