hostapd: Fix clearing up settings for color switch

Settings for color switch (struct cca_settings settings)
is used without zero clearing, which causes the member
settings->ubpr->unsol_bcast_probe_resp_intervalettings
to be a random value. It is againsts the NLA policy of
NL80211_UNSOL_BCAST_PROBE_RESP_ATTR_INT and causes
BSS color switch failure.
