Currently btt replaces the older IO when finding out new IO that is beginning at the same sector.But the older IO will not be released until btt exits, when calling io_free_all(),this is a waste of memory. So,we can free the original IO after replacing it from RB-tree,avoiding useless memory occupation when btt is running.
