Update the doc to reflect the latest implementation, in other words, the debugfs interface 'curr_win_nsec'.

If this latency - is exceeded in a given window of time (see wb_window_usec), then + is exceeded in a given window of time (see curr_win_nsec), then the writeback throttling will start scaling back writes. Writing a value of '0' to this file disables the feature. Writing a value of '-1' to this file resets the value to the default -- 2.25.1
