[PATCH 1/7] blk-cgroup: Kill the header printed at the start of blkio.weight_device file

[Vivek Goyal <vgoyal@redhat.com>]

o Kill extra "dev weight" header which is printed when somebody reads
  blkio.weight_device file. This really seems to be out of convention. No other
  blkio files are printing any header at the start of file. I think it is ok
  to just print values and how to interpret values should be part of
  documentation.
