igc: remove unused autoneg_failed field

autoneg_failed in struct igc_mac_info is never set in the igc driver.
Remove the field and the dead code checking it in
igc_config_fc_after_link_up().

The field originates from the e1000/e1000e fiber/serdes forced-link
path, where MAC-level autoneg timeout sets it to signal the flow-control
code to force pause. igc supports only copper, so it never needs to set
this field.
