gfs2: read journal in large chunks
Use bios to read in the journal into the address space of the journal inode
(jd_inode), sequentially and in large chunks. This is faster for locating the
journal head that the previous binary search approach. When performing
recovery, we keep the journal in the address space until recovery is done,
which further speeds up things.
