[PATCH 10/20] net/failsafe: fix a memory leak in error handling

[Weiguo Li]

When failed at 'rte_intr_efd_enable()', function returned and 'rxq' is
not freed. So free 'rxq' in error handling to avoid a memory leak. We
can't not use 'goto free_rxq' instead since 'rxq' has not assigned to
'dev->data->rx_queues[rx_queue_id]', thus 'fs_rx_queue_release(dev,...)'
will not work in this case.

Fixes: 9e0360aebf236d ("net/failsafe: register as Rx interrupt mode")
