When a PCI error is encountered 6th time in an hour we

However, after upstream commit 38ddc011478e ("powerpc/eeh:
Make permanently failed devices non-actionable"), EEH handler
stops calling any routine once the device is marked as
permanent failure. This issue can lead to fatal consequences
like kernel hang with certain PCI devices.

Applied to powerpc/next.
