read_block bug fixed.
read block should first check whether this block is mapped or not,
if it's not mapped, it should invoke ide_read, but if it has already
been mapped, it just MUST NOT invoke ide_read, because, otherwise,
the modified page would be erased with the data on the disk.
My original implementation didn't handle it well, but now, fixed :-)
