Mohamed Khalfella 54bc741a87 PCI/AER: Iterate over error counters instead of error strings

[ Upstream commit 5e6ae050955b566484f3cc6a66e3925eae87a0ed ]

Previously we iterated over AER stat *names*, e.g.,
aer_correctable_error_string[32], but the actual stat *counters* may not be
that large, e.g., pdev->aer_stats->dev_cor_errs[16], which means that we
printed junk in the sysfs stats files.

Iterate over the stat counter arrays instead of the names to avoid this
junk.

Also, added a build time check to make sure all
counters have entries in strings array.
