Take the return of phy_start_aneg into account so that ethtool will handle
negotiation errors and not silently accept invalid input.

I don't think this description is accurate. If we get to call
phy_start_aneg() with invalid input, then something has already
gone wrong. As Andrew has already explained, an error from this
function means that something went wrong with PHY communication.
All validation should have happened prior to this function being
called.

Thanks.
