[dpdk-dev] [PATCH 1/3] examples/eventdev_pipeline: configure max events based on dev info

From: Pavan Nikhilesh <pbhagavatula at marvell.com>

Some eventdevs support configuring max events to be -1 (open system).
Check eventdev and event port configuration with eventdev info before
configuring them.
