[ Upstream commit f624bb6fad23df3270580b4fcef415c6e7bf7705 ]
If, e.g. in AP mode, the link was already created by userspace
but not activated yet, it has a chandef but the chandef isn't
valid and has no channel. Check for this and ignore this link.
Fixes: 7b0a0e3c3a88 ("wifi: cfg80211: do some rework towards MLO link APIs")
