So currently, the driver merges the identical rates from the policy provided by minstrel (and it try to do the best choice it can in the associated flags) before to sent it to firmware. Until now, when rates are merged, field "count" is set to max(count1, count2). But, it means that the sum of retries for all rates could be far less than initial number of retries. So, this patch changes the value of field "count" to count1 + count2. Thus, sum of all retries for all rates stay the same.
