[XFS] Don't update mtime on rename source 

As reported by Michael-John Turner XFS updates the mtime on the source
inode of a rename call in case it's a directory and changes the parent.

This doesn't make any sense, is not mentioned in the standards and not
performed by any other Linux filesystems so remove it.
