Revert "pack-objects: fix pack generation when using pack_size_limit"
This reverts most of commit a2430dde8ceaaaabf05937438249397b883ca77a.
That commit made the situation better for repositories with relatively
small number of objects. However with many objects and a small pack size
limit, the time required to complete the repack tends towards O(n^2),
or even much worse with long delta chains.
