ext2: Do not update mtime of a moved directory

One of our users is complaining that his backup tool is upset on ext2
(while it's happy on ext3, xfs, ...) because of the mtime change.

The problem is:

mkdir foo
mkdir bar
mkdir foo/a

Now under ext2:
mv foo/a foo/b

changes mtime of 'foo/a' (foo/b after the move). That does not really
make sense and it does not happen under any other filesystem I've seen.

More complicated is:
mv foo/a bar/a

This changes mtime of foo/a (bar/a after the move) and it makes some
sense since we had to update parent directory pointer of foo/a. But
again, no other filesystem does this. So after some thoughts I'd vote
for consistency and change ext2 to behave the same as other filesystems.

Do not update mtime of a moved directory. Specs don't say anything
about it (neither that it should, nor that it should not be updated) and
other common filesystems (ext3, ext4, xfs, reiserfs, fat, ...) don't do
it. So let's become more consistent.

switch ext2 to simple_fsync()

ext2_update_inode() - it's an alias of ext2_write_inode().
