wifi: mac80211: remove shifted rate support
We really cannot even get into this as we can't have a BSS with a 5/10 MHz (scan) width, and therefore all the code handling shifted rates cannot happen. Remove it all, since it's broken anyway, at least with MLO. Signed-off-by: Johannes Berg <johannes.berg@intel.com>
