When compiling with -O1, this error can appear:
lib/librte_eventdev/rte_event_eth_tx_adapter.c:705:6: error:
‘ret’ may be used uninitialized in this function
If tx_queue_id is -1 and nb_queues is 0, then ret is returned
without being initialized.
It is fixed by setting 0 as initial value.
Fixes: a3bbf2e09756 ("eventdev: add eth Tx adapter implementation")
