[PATCH v2 1/3] domain_validate: Refuse VIR_DOMAIN_DEVICE_ADDRESS_TYPE_UNASSIGNED

[Michal Privoznik <mprivozn@xxxxxxxxxx>]

We document that <address type='unassigned'/> can be used only
for <hostdev/>-s. However, corresponding validation rule is
missing. Let's put the rule into hypervisor agnostic part of
validation process so that all drivers can benefit.
