mac80211: avoid duplicate TX path station lookup
Instead of looking up the destination station twice in the TX path (first to build the header, and then for control processing), save it when building the header and use it later in the TX path. To avoid having to look up the station in the many callers, allow those to pass %NULL which keeps the existing lookup. Signed-off-by: Johannes Berg <johannes.berg@intel.com>
