app/testpmd: fix crash on cleanup
Checks
Commit Message
If allocating the ports[] array fails, a crash will occur when shutting
down testpmd since ethdev emits RTE_ETH_EVENT_DESTROY events.
Move init_port() before registering ethdev event handler.

Looks ok to me. Avoids seg_fault, due to Null pointer access.

Applied to dpdk-next-net/main, thanks.
