squashfs4: use upstream xz compression header format
In the upstream kernel and the upstream squashfs4 tools the xz compression header looks the following: struct disk_comp_opts { __le32 dictionary_size; __le32 flags; }; We added some other members and also moved some existing members. Place the members which are already in upstream header at the same position as in that kernel and add our own at the end. The kernel should not have a problem when there are some additional members and just ignore them. Signed-off-by: Hauke Mehrtens <hauke@hauke-m.de>
