rte_event_eth_tx_adapter_queue_add() - add a check
that returns an error if the ethdev the zero Tx queues
configured.

rte_event_eth_tx_adapter_queue_del() - remove the
checks for ethdev queue count, instead check for
queues added to the adapter which maybe different
from the current ethdev queue count.

Fixes: a3bbf2e09756 ("eventdev: add eth Tx adapter implementation")

missing enclosure for queue to avoid side effects, ie.
	if ((queue) != -1 && (uint16_t)(queue)

Another than above nits,

Please send the v3 asap so that I can include it in RC1.
