BFS is a very simple FS and its superblocks contains only static information and is never changed. However, the BFS code for some misterious reasons marked its buffer head as dirty from time to time, but nothing in that buffer was ever changed. This patch removes all the BFS superblock manipulation, simply because it is not needed. It removes: 1. The si_sbh filed from 'struct bfs_sb_info' because it is not needed. We only need to read the SB once on mount to get the start of data blocks and the FS size. After this, we can forget about the SB. 2. All instances of 'mark_buffer_dirty(sbh)' for BFS SB because it is never changed. 3. The '->sync_fs()' method because there is nothing to sync (inodes are synched by VFS). 4. The '->write_super()' method, again, because the SB is never changed.
