event/dlb2: handle enqueuing more than maximum depth

Browse Source 
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 dequeuing correct number of
events as set by max_cq_depth.
