macvlan: disable LRO on lower device instead of macvlan
A macvlan device has always LRO disabled so that calling
dev_disable_lro() on it does nothing. If we need to disable LRO
e.g. because
- the macvlan device is inserted into a bridge
- IPv6 forwarding is enabled for it
- it is in a different namespace than lowerdev and IPv4
forwarding is enabled in it
we need to disable LRO on its underlying device instead (as we
do for 802.1q VLAN devices).
v2: use newly introduced netif_is_macvlan()
