mac80211: revert "wireless: set correct mandatory rate flags"

Revert upstream commit 1bd773c077de "wireless: set correct mandatory rate
flags", as it breaks 11s interoperability: nodes can only associate when
neither or both have this patch. As this is a regression from released
versions, revert to the old code for now.
