cfg80211/mac80211: DFS setup chandef for cac event
To report channel width correctly we have to send correct channel parameters from mac80211 when calling cfg80211_cac_event(). This is required in case of using channel width higher than 20MHz and we have to set correct dfs channel state after CAC (NL80211_DFS_AVAILABLE).
