[libvirt] [PATCH v3 05/15] conf: Add post parse code for mdevs to virDomainHostdevDefPostParse
We need to make sure that if user explicitly provides a guest address
for a mdev device, the address type will be matching the device API
supported on that specific mediated device and error out with an
incorrect XML message.
