[dpdk-dev] [PATCH v2] net/kni: fix rewritten return value

["Min Hu (Connor)" <humin29@huawei.com>]

Return value of function 'eth_kni_dev_stop' passed to 'ret' is
rewritten later, and this is unreasonable.

This patch fixes it.

Fixes: 62024eb82756 ("ethdev: change stop operation callback to return int")
