Ricky Benitez a74b2adae0 block: expose the statistics in blkio.time and blkio.sectors for the root cgroup 
Currently, the io statistics for the root cgroup are maintained, but
they are not shown because the device information is not available at
the point that the root blkio cgroup is created. This patch updates
the device information when the statistics are updated so that the
statistics become visible.
