[PATCH] ext3 xattr: Don't write to the in-inode xattr space of reserved inodes
We are not using the in-inode space for xattrs in reserved inodes because
mkfs.ext3 doesn't initialize it properly. For those inodes, we set
i_extra_isize to 0. Make sure that we also don't overwrite the
i_extra_isize field when writing out the inode in that case. This is for
cleanliness only, and doesn't fix an actual bug.
