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).
