Add check in RAFP to ensure ref passed is an actual instance.

RAFP currently returns instances for invalid refs where the InstanceID doesn't match the classname type (see failing query).

Now that device_type_from_str() allows strings, instead of passing the poolid, pass the classname base. If the InstanceID doesn't match that of a valid pool, rasds_from_pool() will return an empty instance list.

Failing query:
wbemcli ain -ac Xen_ResourceAllocationFromPool 'http://localhost:5988/root/virt:Xen_ProcessorPool.InstanceID="MemoryPool/0"'
