Aside with fixing the errors count CSR usage the commit e2932d1f6f05
("EDAC/synopsys: Read the error count from the correct register") all of
the sudden has also changed the order of the errors status check
procedure. So now the errors handler method first reads the number of CE
and UE and only then makes sure that any of these errors have actually
happened. It doesn't make much sense. Let's fix that by getting back the
procedures order: first check the ECC status, then read the number of
errors.
