afs: Fix getattr to report server i_size on dirs, not local size

Fix afs_getattr() to report the server's idea of the file size of a
directory rather than the local size.  The local size may differ as we edit
the local copy to avoid having to redownload it and we may end up with a
differently structured blob of a different size.

However, if the directory is discarded from the pagecache we then download
it again and the user may see the directory file size apparently change.
