Shouldn't we need TXA_CHECK_TXQ here? If we need only one place, Do we need
macro?

This patch updates the common queue delete code to handle queues that have been added to the adapter (so rte_event_eth_tx_adapter_queue_del() will also work after if its called after calling rte_eth_dev_close())

I won't say we need it, I had it originally in rte_event_eth_tx_adapter_queue_del() as well, I retained it since it eliminated clutter in rte_event_eth_tx_adapter_queue_add().

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.
