From: David Gibson <da...@gibson.dropbear.id.au> The user can explicitly specify a handle via the "handle" property wired to SevGuestState::handle. That gets passed to the KVM_SEV_LAUNCH_START ioctl() which may update it, the final value being copied back to both SevGuestState::handle and SEVState::handle.
AFAICT, nothing will be looking SEVState::handle before it and SevGuestState::handle have been updated from the ioctl(). So, remove the field and just use SevGuestState::handle directly.
