radiotap: Initialize all members in ieee80211_radiotap_iterator_init()

_next_ns_data could look like it would be used uninitialized in
ieee80211_radiotap_iterator_next() to static analyzers. Avoid
unnecessary reports by explicitly initializing all variables in struct
ieee80211_radiotap_iterator. (CID 62878)
