ixgbe: Fix ethtool output with advertised mode.

Ethtool tries to get advertised speed from phy.autoneg_advertised.
However for copper media this wasn't happening until later do to
an other fix which moved mac.ops.setup_link_speed placement in
ixgbe_link_config(). This patch will display the default advertised
speeds if it can't yet get this information from phy.autoneg_advertised.
