Don't care about st_dev in the index file
Thomas Glanzmann points out that it doesn't work well with different
clients accessing the repository over NFS - they have different views
on what the "device" for the filesystem is.
Of course, other filesystems may not even have stable inode numbers.
But we don't care. At least for now.
