Subject: Re: reiserfs broke between 4.9.205 and 4.9.208

Nevermind.  I just wasn't reproducing properly.  Jan's analysis is
right.  The -EOPNOTSUPP change is required so that we get the right
error when explicit xattr operations are performed on a file system
without them.  Prior to this change, we'd get -EOPNOTSUPP by sb->s_xattr
being NULL.

reiserfs_for_each_xattr needs to handle this the same way we already
handle -ENODATA.
