If a port joins a bridge that it can't offload, it will fallback to
standalone mode and software bridging. In this case, we never want to
offload any FDB entries to hardware either.

Fixes: c26933639b54 ("net: dsa: request drivers to perform FDB isolation")

Do you mind if you resend and you explain in the commit message what is
the impact and why you chose this Fixes: tag?
