f2fs: fix lost xattrs of directories
This patch enhances the xattr consistency of dirs from suddern power-cuts. Possible scenario would be: 1. dir->setxattr used by per-file encryption 2. file->setxattr goes into inline_xattr 3. file->fsync In that case, we should do checkpoint for #1. Otherwise we'd lose dir's key information for the file given #2. Signed-off-by: Jaegeuk Kim <jaegeuk@kernel.org>
