edac: i5100 fix initialization code
Allow csrows to properly initialize when the topology only has active
channels on 2 and 3. This new check allows proper detection and
initialization in this topology. Only checking the first mrt that
represented channels 0 and 1 is not sufficient.
I also fixed up the related debug information path. I can submit as a 2nd
patch if needed.
