Daniil Tatianin 0040e48492 net/ethtool/ioctl: return -EOPNOTSUPP if we have no phy stats ...

[ Upstream commit 9deb1e9fb88b1120a908676fa33bdf9e2eeaefce ]

It's not very useful to copy back an empty ethtool_stats struct and
return 0 if we didn't actually have any stats. This also allows for
further simplification of this function in the future commits.
