[RFC 03/18] target/i386: sev: Rename QSevGuestInfo

[David Gibson <david@gibson.dropbear.id.au>]

At the moment this is a purely passive object which is just a container for
information used elsewhere, hence the name.  I'm going to change that
though, so as a preliminary rename it to SevGuestState.

That name risks confusion with both SEVState and SevState, but I'll be
working on that in following patches.
