Convert diag318_test_handler to use vm_create_with_vcpus() and pass around a
'struct kvm_vcpu' object instead of passing around vCPU IDs. Note, this is
a "functional" change in the sense that the test now creates a vCPU with
vcpu_id==0 instead of vcpu_id==6. The non-zero VCPU_ID was 100% arbitrary
and added little to no validation coverage. If testing non-zero vCPU IDs
is desirable for generic tests, that can be done in the future by tweaking
the VM creation helpers.
