Johannes Berg 2a705bc314 wifi: mac80211: check link exists before use
If the assoc link doesn't exist yet at this point, we
cannot use it yet. This isn't normally the case, but
e.g. in case of FT-DS (or just broken userspace) the
link might not be set up yet and will only be created
later in this function. Check that the link exists.
