[PATCH v3 5/5] ethdev: fix dev state when stop

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

Currently, 'dev_started' is always set to be 0 when dev stop, whether
it succeeded or failed. This is unreasonable and this patch fixed it.

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