KVM: selftests: Remove duplicate LAUNCH_UPDATE_VMSA call in SEV-ES migrate test

Drop the explicit KVM_SEV_LAUNCH_UPDATE_VMSA call when creating an SEV-ES
VM in the SEV migration test, as sev_vm_create() automatically updates the
VMSA pages for SEV-ES guests. The only reason the duplicate call doesn't
cause visible problems is because the test doesn't actually try to run the
vCPUs. That will change when KVM adds a check to prevent userspace from
re-launching a VMSA (which corrupts the VMSA page due to KVM writing
encrypted private memory).
