[dpdk-dev] [PATCH 08/10] crypto/virtio: fix return values check error

[Min Hu (Connor)]

From: HongBo Zheng <zhenghongbo3 at huawei.com>

In virtio_crypto_pkt_tx_burst, we check the return values of
virtqueue_crypto_enqueue_xmit, which may returns -ENOSPC/-EMSGSIZE,
but we only check ENOSPC/EMSGSIZE, and cause the result of checks
is always false.

This patch fix this problem.

Fixes: 82adb12a1fce ("crypto/virtio: support burst enqueue/dequeue")
