Heiner reported that the commit in question prevents his network adapter from triggering PME and waking up when network cable is plugged. The commit tried to prevent root port waking up from D3cold immediately but looks like disabing root port PME interrupt is not the right way to fix that issue so revert it now. The patch following proposes an alternative solution to that issue.
