Fix management of backed-up region for hi-to-low reshapes.

When reshaping from the end of the array to the start, for times
when the number of data devices is decreasing, the handling of the
backup area isn't a simple mirror of the handling on low-to-hi
reshapes as the backup areas is always low in the array.

So re-write that to make it work.
