net/i40e/base: fix PHY config param when enabling EEE

The i40e_enable_eee function did not copy phy_type_ext field
from current PHY configuration retrieved with Get PHY Abilities AQ.
It caused a misconfiguration of the PHY on devices supporting 2.5
and 5G speeds and prevented establishing link when only those
speeds were selected for advertisement.
