wifi: mac80211: recalc min chandef for new STA links

BugLink: https://bugs.launchpad.net/bugs/2034469
[ Upstream commit ba7af2654e3b7b810c750b3c6106f6f20b81cc88 ]

When adding a new link to a station, this needs to cause a
recalculation of the minimum chandef since otherwise we can
have a higher bandwidth station connected on that link than
the link is operating at. Do the appropriate recalc.
