But then I tested it ...
I injected a UC error to memory - then did a simple byte write to the target
line.

Until now, the mce_severity mechanism can only identify the severity
of UCNA error as MCE_KEEP_SEVERITY. Meanwhile, it is not able to filter
out DEFERRED error for ADM platform.
This patch aims to extend the mce_severity mechanism for handling
UCNA/DEFERR
