Johannes Berg dfe9a04330 wifi: mac80211: prohibit deactivating all links 
[ Upstream commit 7553477cbfd784b128297f9ed43751688415bbaa ]

In the internal API this calls this is a WARN_ON, but that
should remain since internally we want to know about bugs
that may cause this. Prevent deactivating all links in the
debugfs write directly.
