mac80211: minstrel, fix memory corruption
minstrel doesn't count max rate count in fact, since it doesn't use a loop variable `i' and hence allocs space only for bitrates found in the first band. Fix it by involving the `i' as an index so that it traverses all the bands now and finds the real max bitrate count.
