This patch addresses an issue of enqueuing more than max_enq_depth and not able to dequeuing events equal to max_cq_depth in a single call of rte_event_enqueue_burst and rte_event_dequeue_burst.
Apply fix for restricting enqueue of events to max_enq_depth so that in a single rte_event_enqueue_burst() call at most max_enq_depth events are enqueued. Also set per port and domain history list sizes based on cq_depth. This results in dequeing correct number of events as set by max_cq_depth.
