From: Oza Pawandeep <[email protected]> pci_cleanup_aer_uncorrect_error_status() is called by driver .slot_reset() methods when handling ERR_NONFATAL errors. Previously this cleared *all* the bits, including ERR_FATAL bits.
Since we're only handling ERR_NONFATAL errors, clear only the ERR_NONFATAL error status bits.
