igb: do not overwrite EEPROM LED settings

The igb driver was overwritting the LED settings that were configured via
EEPROM.  This is not correct behavior as the LED settings are meant to be
configured by EEPROM and not changed.  This change removes the code that
was setting the LED behavior on the interface.
