Fix BlockStorageAttachment bug when translate compute node

Currently, when translate compute node with local_storage and
high_availability, there is not BlockStorageAttache resource created
about block storage, and only BlockStorage created.
If only local_storage requirement in compute node, the result is
correct.
The reason is the function logic of _get_attachment_node is error. and
the patch will fixit.
