net: stmmac: fix .ndo_fix_features()
netdev features documentation requires that .ndo_fix_features() is
stateless: it shouldn't modify driver state. Yet, stmmac_fix_features()
does exactly that, changing whether GSO frames are processed by the
driver.
Move this code to stmmac_set_features() instead, which is the correct
place for it. We don't need to check whether TSO is supported; this
is already handled via the setup of netdev->hw_features, and we are
guaranteed that if netdev->hw_features indicates that a feature is
not supported, .ndo_set_features() won't be called with it set.
