[dpdk-dev] [PATCH v3] app/eventdev: detect deadlock for timer event producer

If timer events get dropped for some reason, the thread that launched
producer and worker cores will never exit, because the deadlock check
doesn't currently apply to the event timer adapter case. This commit
fixes this.

Fixes: d008f20bce23 ("app/eventdev: add event timer adapter as a
producer")
