[RFC] mac80211: clear radar_required while setting up sdata

[Rajkumar Manoharan]

The commit "mac80211: don't defer scans in case of radar detection"
drops scan requests when interface is running on radar channel.
Once the AP interface is brought up on DFS channel,
sdata->radar_required never be cleared on deinit path unless the
interface is deleted. This is causing failures while restarting hostapd.
