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.
