do not hide DFS channels in luci web-interface

see https://dev.openwrt.org/ticket/14919

Channels with the "restricted" flag are not shown by luci.
Any channel with one of the following attributes is marked as "restricted" by
iwinfo:
* NL80211_FREQUENCY_ATTR_PASSIVE_SCAN
* NL80211_FREQUENCY_ATTR_NO_IBSS
* NL80211_FREQUENCY_ATTR_RADAR

The patch removes NL80211_FREQUENCY_ATTR_RADAR from the above list. Thus DFS
channels are displayed.

Sadly no visual indication is given if the current wireless driver supports DFS.
Thus hostapd may refuse to select the configured channel without any further
explanation.
