Pull AFS fixes from David Howells:

 - Fix an oops in AFS that can be triggered by accessing one of the
   afs.yfs.* xattrs against an OpenAFS server - for instance by commands
   like "cp -a"[1], "rsync -X" or getfattr[2]. These try and copy all of
   the xattrs.

   cp and rsync should pay attention to the list in /etc/xattr.conf, but
   cp doesn't on Ubuntu and rsync doesn't seem to on Ubuntu or Fedora.
   xattr.conf has been modified upstream[3], and a new version has just
   been cut that includes it. I've logged a bug against rsync for the
   problem there[4].

 - Stop listing "afs.*" xattrs[5][6][7], but particularly ACL ones[8] so
   that they don't confuse cp and rsync.

   This removes them from the list returned by listxattr(), but they're
   still available to get/set.
