This reverts commit 9f55f36f749a7608eeef57d7d72991a9bd557341.

This patch was backported incorrectly when Sasha backported it 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.
