Static checkers complain that we should maybe set "ret" before we do the
"goto out;". They interpret the NULL return from br_port_get_rtnl() as
a failure and forgetting to set the error code is a common bug in this
situation.
The code is confusing but it's actually correct. We are returning zero
deliberately. Let's re-write it a bit to be more clear.
