KVM: SEV: Init target VMCBs in sev_migrate_from

Browse source

The target VMCBs during an intra-host migration need to correctly setup
for running SEV and SEV-ES guests. Add sev_init_vmcb() function and make
sev_es_init_vmcb() static. sev_init_vmcb() uses the now private function
to init SEV-ES guests VMCBs when needed.
