libwifi: nlwifi: do not clear radio supp_bw
This patch fix empty supp_bw field in radio status ubus call: ubus call wifi.radio.phyX status
When using NL80211_ATTR_SPLIT_WIPHY_DUMP we can not clear radio structure memory in parsing callbacks because data for single wiphy is split across multiple messages. When data are set correctly during one iteration it was cleared in another iteration.
