wifi: mac80211: skip NSS and BW init for S1G sta

Browse source

Currently there is no S1G STA bandwidth support throughout mac80211
as existing support is all based on 20MHz widths. With the recent
STA NSS/BW handling rework, S1G associations now hit the new WARN within
ieee80211_chan_width_to_rx_bw() as the chandef is not a 20MHz based
width. For now, skip initialisating link_sta->pub->bandwidth for
S1G chandefs to avoid the WARN though this should at some point be
properly implemented since there are vendors that offer differing
maximum bandwidths.

Additionally, currently all S1G hardware out there is 1SS so rather
then introducing new parsing code which wouldn't be used anyway, just
initialise the NSS related fields to 1 and skip initialising the STA
bandwidth for S1G chandefs within ieee80211_sta_init_nss_bw_capa().
