Matthew Rosato f69350e8bd ap_tools/ap-check: reject start for control domains without usage ...

When configuring a vfio-ap device, specifying only control domains
without any usage domains results in a useless configuration in that
both adapters and usage domains are required to make cryptographic
resources available to the guest.  Without that, the control domains
are useless.  While the kernel allows this, let's reject this
combination with a message.
