More safe chain sorting, improving r7098
This patch is an improvment of r7098 (made by me).
Assuring compatibility between 1.4.0 and older versions,
regarding chain sorting.
Chains from kernel are already sorted, as they are inserted
sorted. But there exists an issue when shifting to 1.4.0
from an older version, as old versions allow last created
chain to be unsorted. This unsorted chain would survive in
1.4.0, as chains are now only sorted on creation.
This patch verifies that chains are sorted, if not it fixes the sorting.
