ixgbe: Fix 82599 KX4 Wake on LAN issue after an improper system shutdown
Advanced Power Management is disabled for 82599 KX4 connections by clearing GRC.APME bit, causing it to not wake the system from an improper system shutdown. By default GRC.APME is enabled and software is not supposed to clear these settings during adapter probe.
