This makes cu_compare_ref() assist association providers in avoiding
carefully crafted instances to fool the dispatch code.  For example,
in HostedResourcePool, it (now) uses cu_compare_ref() to make sure the
client specified a valid HostSystem, but since ComputerSystem is a
CIM_System, if you pass ComputerSystem.Name="<hostname_of_system>",
HostedResourcePool would validate Name and proceed.
