[ Upstream commit 59f58708c5047289589cbf6ee95146b76cf57d1e ]
e1000e sets different WoL settings in system suspend callback and runtime suspend callback.
The suspend direct complete optimization leaves e1000e in runtime suspended state with wrong WoL setting during system suspend.
To fix this, we need to disable suspend direct complete optimization to let e1000e always use suspend callback to set correct WoL during system suspend.
