    Avoid unnecessary joins in delete_resource_provider

    If cascade=True, we're getting all of the instances on the
    compute node just to use the uuid, which will by default
    join on the info_cache and security_groups for the instances.
    This is a simple optimization to avoid those unnecessary joins.

    A TODO is left to further optimize this with a new InstanceList
    query method to just get the instance uuids on a given host/node
    combo, but that requires an RPC change which we can't backport.
