PCI: Clear AER uncorrectable status according to error types

Commit Message

The AER recovery process use pci_aer_clear_nonfatal_status() to clear
non-fatal error status after successfully recovering from non-fatal error.
However, the fatal error status clearing for successful recovery of AER
fatal error was overlooked.
Therefore, this patch wants:
When the error type is non-fatal, use pci_aer_clear_nonfatal_status()
to clear non-fatal error status.
When the error type is fatal, use pci_aer_clear_fatal_status()
to clear fatal error status.
