drivers/net: remove duplicate structure field initialization

The definitions of vnet_ops and ehea_netdev_ops have initializations of a
local function and eth_change_mtu for their respective ndo_change_mtu
fields.  This change uses only the local function.

The semantic match that finds this problem is as follows:
