[PULL,102/115] target/i386: sev: Rename QSevGuestInfo

Commit Message

Paolo Bonzini June 11, 2020, 7:44 p.m. UTC

From: David Gibson <[e-mail]>

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.
