mac80211: get correct default channel width for S1G
When deleting a channel context, mac80211 would assing NL80211_CHAN_WIDTH_20_NOHT as the default channel width. This is wrong in S1G however, so instead get the allowed channel width for a given channel. Fixes eg. configuring strange (20Mhz) width during a scan on the S1G band.
