[dpdk-dev] [PATCH] net/netvsc: fix txq leak in error path

[wangyunjian]

From: Yunjian Wang <wangyunjian at huawei.com>

In hn_dev_tx_queue_setup() allocated memory for txq,
we should free it when error happens, otherwise it
will lead to memory leak.

Fixes: cc0251813277 ("net/netvsc: split send buffers from Tx descriptors")
