Since we're not saving the platform-specific data into a cache, we're not going to populate the structure, which in turn will cause a crash upon calling virNodeGetSEVInfo because of a NULL pointer dereference. Ultimately, we should start caching this data along with host-specific capabilities like NUMA and SELinux stuff into a separate cache, but for the time being, this is a semi-proper fix for a potential crash.

ACK. I could not find any place where the data would be used by any code which would get it from the local copy from the @vm object, since that is not serialized in the domain status XML.
