udf: Mark LVID buffer as uptodate before marking it dirty

commit 853a0c25baf96b028de1654bea1e0c8857eadf3d upstream.

When we hit EIO while writing LVID, the buffer uptodate bit is cleared.
This then results in an anoying warning from mark_buffer_dirty() when we
write the buffer again. So just set uptodate flag unconditionally.
