e1000e: Serdes - attempt autoneg when link restored.
This patch addresses an issue where we did not restart auto-negotiation on serdes links when the link partner was disabled and re-enabled. It includes reworking the serdes link detect mechanism to be a state machine for 82571 and 82572 parts only.
