KVM: SVM: Do not set sev->es_active until KVM_SEV_ES_INIT completes
Set sev->es_active only after the guts of KVM_SEV_ES_INIT succeeds. If
the command fails, e.g. because SEV is already active or there are no
available ASIDs, then es_active will be left set even though the VM is
not fully SEV-ES capable.
Refactor the code so that "es_active" is passed on the stack instead of
being prematurely shoved into sev_info, both to avoid having to unwind
sev_info and so that it's more obvious what actually consumes es_active
in sev_guest_init() and its helpers.
