mac80211: remove tracing config symbol
There's little point in this config symbol, if tracing is disabled the overhead is negligible and if you think it's too bad you can always turn off tracing completely. Also remove the part where we don't have sparse check the tracing code -- it seems that it can now deal with it (or the code changed).
