app/eventdev: remove redundant enqueue in burst Tx

[ upstream commit 21b1ca4 ]

For eventdev pipeline test, in burst_tx cases, there is no needed to
set ev.op as RTE_EVENT_OP_RELEASE and call pipeline_event_enqueue_burst
to release events. This is because for tx mode(internal_port=true),
the capability "implicit_release" of dev is enabled, and the app can
release events by "rte_event_dequeue_burst" rather than enqueue.

Fixes: 314bcf5 ("app/eventdev: add pipeline queue worker functions")
