wifi: mac80211: clean up band switch in duration
Most devices now do duration calculations, so we don't hit this code at all any more. Clearly the approach of warning at compile time here when new bands are added didn't work, the new bands were just added with "TODO". Clean it up, it won't matter for new bands since they'll just not have any need to calculate durations in software. While at it, also clean up and unify the code a bit.
