Jan Kara 52a366e0f6 char: Mark /dev/zero and /dev/kmem as not capable of writeback ...

commit 371d217ee1 upstream.

These devices don't do any writeback but their device inodes still can get
dirty so mark bdi appropriately so that bdi code does the right thing and files
inodes to lists of bdi carrying the device inodes.
