btrfs: defrag: use a single list for each loop in defrag_one_range()

There's no need to have one list for each loop to defrag each subrange and
then another one to free each subrange (struct defrag_target_range).
We can do it in a single loop, freeing each subrange after defragging,
plus no need to delete each subrange from the list since we immediately
free it.
