KVM: Shove vm stats_id init into kvm_create_vm()

Initialize stats_id alongside other struct kvm fields to make it more difficult to unintentionally access stats_id before it's set. While at it, move the format string to the first line of the call and fix the indentation of the second line. No functional change intended.
