PCI/AER: Use a common function to print AER error bits

Commit Message

Alex G. March 29, 2018, 9:24 p.m. UTC

On errors reported from CPER, cper_print_bits() was used to log the
AER bits. This resulted in hard-to-understand messages, without a
prefix. Instead use __aer_print_error() for both native AER and CPER
to provide a more consistent log format.
