ethtool: Fix get module eeprom fallback

ethtool: Fix get module eeprom fallback

Function fallback_set_params() checks if the module type returned
by a driver is ETH_MODULE_SFF_8079 and in this case it assumes
that buffer returns a concatenated content of page  A0h and A2h.
The check is wrong because the correct type is ETH_MODULE_SFF_8472.
