PCI: pcie, aer: report all error before recovery
This patch is required not to lost error records by action invoked on
error recovery, such as slot reset etc.
Following sample (real machine + dummy record injected by aer-inject)
shows that record of 28:00.1 could not be retrieved by recovery of 28:00.0:
