[PATCH] app/testpmd: fix crash on cleanup

[David Marchand <david.marchand@redhat.com>]

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.

Fixes: 85c6571c9103 ("app/testpmd: reset port status on close notification")
