PATCH ext4: fix to call_filldir

[curtw@google.com (Curt Wohlgemuth)]

[ Sorry: I mistakenly sent just the patch, with no explanation... ]

I happened to find a bug running bonnie++-1.03a on an ext4 filesystem, when
it complained about not being able to remove a file.

Further investigation showed a problem with call_filldir(), which is not
quite correct with respect to the same function in fs/ext3/dir.c.  The patch
below fixes this problem.
