[PATCH v4 2/6] net/netvsc: fix double-free of primary Rx queue on uninit

[Long Li]

eth_hn_dev_uninit() calls hn_dev_close() which calls hn_dev_free_queues()
that frees all rx queues including hv->primary via hn_rx_queue_free(rxq,
false). After that, eth_hn_dev_uninit() calls rte_free(hv->primary) again,
resulting in a double-free.

Remove the redundant rte_free(hv->primary) since hn_dev_free_queues()
already handles freeing it.
