Subject: igb: Exclude device from suspend direct complete optimization
Patch-mainline: v5.2-rc1
Git-commit: 5b6e13216be29ced7350d9c354a1af8fe0ad9a3e
References: jsc#SLE-4798

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.
