when a new gateway(never joined a cluster before) joined a existing clsuter. `dog vdi object location` causes the new gateway exist because its backend storage is not initialized. this patch solves this problems by checking whether a node is gateway in `local_oid_exist` fucntion. simple return `SD_RES_NO_OBJ` to avoid using uninitialized pointer.
