There are several error paths where the bonding device may not start.
Don't set dev_started until we know that we are sure start is going
to succeed.

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.

Hi Chas,
Is this patch still valid to consider for v18.08?

No. This was fixed by
net/bonding: clear started state if start fails
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.

which was less clumsy attempt at the fix.
