ext4: use proper csum calculation in ext4_rename
commit ef58f69c3c34f6377f1e21d3533c806dbd980ad0 upstream. In ext4_rename, when the old name is a dir, we need to change ".." to its new parent and journal the change, so with metadata_csum enabled, we have to re-calc the csum. As the first block of the dir can be either a htree root or a normal directory block and we have different csum calculation for these 2 types, we have to choose the right one in ext4_rename. btw, it is found by xfstests 013.
