[PATCH 2/4] RNR: add bss_parameters to the neighbor_db

[John Crispin]

P802.11ax/D4.0 9.4.2.170 (Reduced Neighbor Report element) described this
field used inside reduced neighbor reports. It holds info about multiple
bssid and 6G co-location which was not present in the existing neighbor
reports.
