net: sysfs: ethtool_ops can be NULL
commit d519e17e2d01a0ee9abe083019532061b4438065
(net: export device speed and duplex via sysfs)
made the wrong assumption that netdev->ethtool_ops was always set.
This makes possible to crash kernel and let rtnl in locked state.
modprobe dummy
ip link set dummy0 up
(udev runs and crash)
