[PATCH] afs: Revert "afs: Hide silly-rename files from userspace"

[David Howells <dhowells@redhat.com>]

    
This reverts commit 57e9d49c54528c49b8bffe6d99d782ea051ea534.

This undoes the hiding of .__afsXXXX silly-rename files.  The problem with
hiding them is that rm can't then manually delete them.

This also reverts commit 5f7a07646655fb4108da527565dcdc80124b14c4 ("afs: Fix
endless loop in directory parsing") as that's a bugfix for the above.
