wifi: cfg80211: report per-link errors during association

Browse source

When one of the links (other than the assoc_link) is misconfigured
and cannot work the association will fail. However, userspace was not
able to tell that the operation only failed because of a problem with
one of the links. Fix this, by allowing the driver to set a per-link
error code and reporting the (first) offending link by setting the
bad_attr accordingly.

This only allows us to report the first error, but that is sufficient
for userspace to e.g. remove the offending link and retry.
