wireless: Only join DFS channels in mesh mode if userspace flags support
When joining a mesh network it is not guaranteed that userspace has a daemon listening for radar events. This is however required for channels requiring DFS. To flag that userspace will handle radar events, it needs to set NL80211_ATTR_HANDLE_DFS. This matches the current mechanism used for IBSS mode.
