net80211/drivers: improve ieee80211_rx_stats for band
While IEEE80211_R_BAND was defined, there was no place to store the band. Add a field for that, adjust ieee80211_lookup_channel_rxstatus() to require it, and update drivers passing "R_{FREQ|IEEE}" in already to provide the band as well. For the moment keep the fall-back code requiring all three fields. Sponsored by: The FreeBSD Foundation MFC after: 3 days Reviewed by: adrian Differential Revision: https://reviews.freebsd.org/D30662
