wifi: iwlwifi: mvm: Don't set NO_HT40+/- flags on 6 GHz band

Browse Source 
These flags are not needed on 6 GHz channels, and anyway they were set
incorrectly.
This in turn resulted in alternating channel flags, preventing reg domain
rules to be merged together, so cfg80211 couldn't even send them to the
user space, as the regulatory domain was too large.
Fix it.
