[SRU][BIONIC][PATCH 1/1] ipvlan: use ETH_MAX_MTU as max mtu

[Nivedita Singhvi]

From: Xin Long <lucien.xin at gmail.com>

BugLink: https://bugs.launchpad.net/bugs/1879658

Similar to the fixes on team and bonding, this restores the ability
to set an ipvlan device's mtu to anything higher than 1500.

Fixes: 91572088e3fd ("net: use core MTU range checking in core net infra")
