This reverts commit 7b0db849ea030a70b8fb9c9afec67c81f955482e.

The patches that this patch depends on were not backported properly
and the patch that caused the regression that this patch set fixed
was reverted in commit 412b844143e3 ("Revert "PCI/portdrv: Don't disable AER reporting in get_port_device_capability()"").
This isn't necessary and causes a regression so drop it.
