event/dsw: ignore scheduling type for single-link queues

The scheduling type parameter is not applicable for single link
queues. DSW would, at the time of rte_event_queue_setup(), erroneously
verify that scheduling type was one of the supported types, and
returned -ENOTSUP in case of RTE_SCHED_TYPE_ORDERED.
