[dpdk-stable] [PATCH v1 1/2] app/eventdev: adjust event count order for pipeline test

[Feifei Wang <feifei.wang2@arm.com>]

For the fwd mode (internal_port = false) in pipeline test,
processed-pkts increment should after enqueue. However, in
multi_stage_fwd and multi_stage_burst_fwd, "w->processed_pkts" is
increased before enqueue.

To fix this, move "w->processed_pkts" increment after enqueue, and then
the main core can load the correct number of processed packets.

Fixes: 314bcf58ca8f ("app/eventdev: add pipeline queue worker functions")
