So renaming ghes_deferrable_severity() to ghes_actual_severity() is not
a big change. And that's not what I meant.

I'd like to see here:

		 sev = ghes_severity(ghes);

and inside you do all the required mapping/severity processing/etc. And
you can rename the current ghes_severity() to ghes_map_cper_severity()
or whatever...

... so that this change doesn't happen and there are not two severities
queried but a single one.
