afs: Revert "afs: Hide silly-rename files from userspace"

[ Upstream commit 0aec3847 ]

This reverts commit 57e9d49c.

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 5f7a0764 ("afs: Fix
endless loop in directory parsing") as that's a bugfix for the above.

Fixes: 57e9d49c
