bcache: store a pointer to the on-disk sb in the cache and cached_dev structures
This allows to properly build the superblock bio including the offset in
the page using the normal bio helpers. This fixes writing the superblock
for page sizes larger than 4k where the sb write bio would need an offset
in the bio_vec.
