Subject: [PATCH v1 17/18] KVM: selftests: remove the *vcpu[] input from __vm_create_with_vcpus
kvm_vm has included an array of vcpu pointers (i.e. *vcpu[]) to the
added vcpus, so there is no need for users to supply its own *vcpu[].
Remove the *vcpu[] from __vm_create_with_vcpus and the related callers.
