KVM: SEV: Allow some commands for mirror VM
A mirrored SEV-ES VM will need to call KVM_SEV_LAUNCH_UPDATE_VMSA to
setup its vCPUs and have them measured, and their VMSAs encrypted. Without
this change, it is impossible to have mirror VMs as part of SEV-ES VMs.
Also allow the guest status check and debugging commands since they do
not change any guest state.
