[Patch] AMD64_EDAC: simple fix to allow better report on ECE CEerrors

[Keith Mannthey]

I tested 2.6.31 and the mainline amd64_edac driver. This is was the
first simple fix.  

This allows the errors to be further decoded and mapped to csrows. 
Tested with ECC debug dimms and an Rev F cpu based system.
