test/event: fix crash in Tx adapter freeing

[ upstream commit 1f85467fcaf03c6b0d879614ee18f9a98fe9e9e6 ]

Uninitialized mbufs are enqueued to eventdev which causes segfault
on freeing the mbuf in Tx adapter.
Fixed by initializing mbufs before enqueuing to eventdev.

Fixes: 46cf97e ("eventdev: add test for eth Tx adapter")
