[dpdk-dev] [PATCH] event/octeontx: fix memory corruption

[Harman Kalra]

Since PMD enqueues a single event at a time, fixing the issue by
passing 1 rather than nb_events to avoid any out of bound access as
reported by coverity.

Coverity issue: 358447
Fixes: 56a96aa42464 ("event/octeontx: add framework for Rx/Tx offloads")
