Subject: pci: Revive pci_dev __aer_firmware_first* fields for kABI
Patch-mainline: Never, kABI compatibility fix
References: bsc#1174356

The upstream commit 708b20003624 ("PCI/AER: Remove HEST/FIRMWARE_FIRST
parsing for AER ownership") removed two unused fields from pci_dev
struct, and this broke kABI.

Revive those fields to keep the kABI compatibility.
They are just placeholders without actual usage.
