[dpdk-dev] [PATCH v2] net/bonding: clear dev_started if start fails

[Chas Williams <3chas3@gmail.com>]

From: "Charles (Chas) Williams" <chas3@att.com>

There are several error paths where the bonding device may not start.
Clear dev_started before we return if we take one of these paths.

Fixes: 2efb58cbab ("bond: new link bonding library")
Cc: stable@dpdk.org
