Jakub Kicinski 82274d0755 devlink: ignore -EOPNOTSUPP errors on dumpit
Number of .dumpit functions try to ignore -EOPNOTSUPP errors.
Recent change missed that, and started reporting all errors
but -EMSGSIZE back from dumps. This leads to situation like
this:

$ devlink dev info
devlink answers: Operation not supported

Dump should not report an error just because the last device
to be queried could not provide an answer.

To fix this and avoid similar confusion make sure we clear
err properly, and not leave it set to an error if we don't
terminate the iteration.

Fixes: c62c2cfb80 ("net: devlink: don't ignore errors during dumpit")
