e1000e: Incorrect function pointer set for force_speed_duplex on 82577

The force_speed_duplex function pointer was incorrectly set.  Instead of
calling the 82577-specific version it was calling the m88 version which,
among other incorrect things, reset the PHY causing autonegotiation to be
re-enabled in the PHY resulting in the link defaulting to half-duplex.
The 82577-specific force_speed_duplex function also had an issue where
it disabled Auto-MDI-X which caused the link to not come up.
