[PATCH net-next v2 4/4] net: no need to disable LRO specifically

[Hangbin Liu <liuhangbin@gmail.com>]

In commit "net: use ndo_set_features to set offload features for
bonding/bridge/team" we called netdev_change_features() in
__netdev_upper_dev_link(), which will disable LRO automatically on lower
device if upper device doesn't have LRO enabled. So we don't need to
dev_disable_lro() again after netdev_upper_dev_link().
