Subject: [net-next 02/10] igb: Exclude device from suspend direct complete optimization

From: Kai-Heng Feng <kai.heng.feng@...onical.com>

igb sets different WoL settings in system suspend callback and runtime
suspend callback.

The suspend direct complete optimization leaves igb in runtime suspended
state with wrong WoL setting during system suspend.

To fix this, we need to disable suspend direct complete optimization to
let igb always use suspend callback to set correct WoL during system
suspend.
