The legacy ethtool userspace tool shows an error when no features could
be changed. It's useful to have a netlink reply to be able to show this
error when __netdev_update_features wasn't called, for example:
1. ethtool -k eth0
large-receive-offload: off
2. ethtool -K eth0 rx-fcs on
3. ethtool -K eth0 lro on
Could not change any device features
rx-lro: off [requested on]
4. ethtool -K eth0 lro on
# The output should be the same, but without this patch the kernel
# doesn't send the reply, and ethtool is unable to detect the error.
This commit makes ethtool-netlink always return a reply when requested,
and it still avoids unnecessary calls to __netdev_update_features if the
wanted features haven't changed.
