wifi: cfg80211: fix regulatory disconnect for non-MLO 

commit b22552fcaf upstream.

The multi-link loop here broke disconnect when multi-link
operation (MLO) isn't active for a given interface, since
in that case valid_links is 0 (indicating no links, i.e.
no MLO.)

Fix this by taking that into account properly and skipping
the link only if there are valid_links in the first place.
