PCI/AER: Use 'Correctable' and 'Uncorrectable' spec terms for errors
The PCIe spec classifies errors as either "Correctable" or "Uncorrectable".
Previously we printed these as "Corrected" or "Uncorrected". To avoid
confusion, use the same terms as the spec.
One confusing situation is when one agent detects an error, but another
agent is responsible for recovery, e.g., by re-attempting the operation.
The first agent may log a "correctable" error but it has not yet been
corrected. The recovery agent must report an uncorrectable error if it is
unable to recover. If we print the first agent's error as "Corrected", it
gives the false impression that it has already been resolved.
Sample message change:
- pcieport 0000:00:1c.5: AER: Corrected error received: 0000:00:1c.5
+ pcieport 0000:00:1c.5: AER: Correctable error received: 0000:00:1c.5
