Subject: [PATCH 077/359] DDF: _write_super_to_disk: fix anchor header type
References: bsc#1081910

Since commit 30bee0201, the anchor is updated from the active
DDF header. This requires fixing the header type before the
anchor is written.

The LSI Software RAID code will reject DDF meta data with wrong
anchor type and will erase all meta data when it encounters
such a broken anchor. Thus starting Linux md once on a system
with LSI RAID BIOS may cause the meta data to get destroyed.
