(POOLER-147) Fix create_linked_clone pool option

This commit updates the create_linked_clone pool option to correctly detect when linked clones have been set at a pool level. Without this change a pool setting create_linked_clone to false is not interpreted correctly, and a linked clone is created if possible.
