wifi: mac80211: add ieee80211_vif_link_active() helper
We sometimes need to check if a link is active, and this
is complicated by the fact that active_links has no bits
set when the vif isn't (acting as) an MLD. Add a small
new helper ieee80211_vif_link_active() to make that a bit
easier, and use it in a few places.
