wifi: nl80211: reject S1G/60G with HT chantype
This configuration doesn't make sense, neither S1G nor
60G have 20 or 40 MHz channel width. Reject it to not
run into the new cfg80211_chandef_create() warning.
Fixes: 92d77e06e73c ("wifi: cfg80211: restrict cfg80211_chandef_create() to only HT-based bands")
