KVM: SEV: Move init of SNP guest state into sev_init_vmcb()

Browse source

Move the initialization of SNP guest state from svm_vcpu_reset() into
sev_init_vmcb() to reduce the number of paths that deal with INIT/RESET
for SEV+ vCPUs from 4+ to 1.  Plumb in @init_event as necessary.

Opportunistically check for an SNP guest outside of
sev_snp_init_protected_guest_state() so that sev_init_vmcb() is consistent
with respect to checking for SEV-ES+ and SNP+ guests.

No functional change intended.
