net: ena: Destroy correct number of xdp queues upon failure
The ena_setup_and_create_all_xdp_queues() function freed all the
resources upon failure, after creating only xdp_num_queues queues,
instead of freeing just the created ones.
In this patch, the only resources that are freed, are the ones
allocated right before the failure occurs.
Fixes: 548c4940b9f1 ("net: ena: Implement XDP_TX action")
