wifi: cfg80211: stop radar detection in cfg80211_leave()

Browse source

[ Upstream commit 9f33477b9a ]

If an interface is set down or, per the previous patch, changes
type, radar detection for it should be cancelled. This is done
for AP mode in mac80211 (somewhat needlessly, since cfg80211 can
do it, but didn't until now), but wasn't handled for mesh, so if
radar detection was started and then the interface set down or
its type switched (the latter sometimes happning in the hwsim
test 'mesh_peer_connected_dfs'), radar detection would be around
with the interface unknown to the driver, later leading to some
warnings around chanctx usage.
