fbdefio: add set_page_dirty handler to deferred IO FB
commit d847471d063663b9f36927d265c66a270c0cfaab upstream
Fixes kernel BUG at lib/radix-tree.c:473.
Previously the handler was incidentally provided by tmpfs but this was
removed with:
commit 14fcc23fdc78e9d32372553ccf21758a9bd56fa1

tmpfs: fix kernel BUG in shmem_delete_inode
relying on this behaviour was incorrect in any case and the BUG also
appeared when the device node was on an ext3 filesystem.
v2: override a_ops at open() time rather than mmap() time to minimise
races per AKPM's concerns.
