[PATCH] corruption checker: print the DMI board name

[Arjan van de Ven]

when the memory corruptor checker hits (as it has done now based on kerneloops.org data),
it would be extremely useful to know the DMI board name so we can add a blacklist for
such a machine... without having to ask the user for lots of extra info.
