Bug Description

---Problem Description---
WARNING: at /build/linux-aWXT0l/linux-4.4.0/drivers/pci/pci.c:1595 [travis3EN]

---uname output---
Linux ltciofvtr-s822l2-lp3 4.4.0-4-generic #19-Ubuntu SMP Fri Feb 5 17:36:21 UTC 2016 ppc64le ppc64le ppc64le GNU/Linux

Machine Type = s822l

---Steps to Reproduce---
 triggering EEH causes the warning messages in syslog
Note: its just the warning messages, card recovers after EEH

1. from peer: run some load
linux-xqxs:~ # ping -f 22.22.22.22

2. from pKVM host run the EEH for the travis3EN card
[root@ltciofvtr-s822l2-lp1 ~]# echo 0x8000000000000000 > /sys/kernel/debug/powerpc/PCI0003/err_injct_inboundA; sleep 1; echo 0x0 > /sys/kernel/debug/powerpc/PCI0003/err_injct_inboundA

3. on client's sysfs you can see the warning messages "WARNING: at /build/linux-aWXT0l/linux-4.4.0/drivers/pci/pci.c:1595"
