[LTP] [PATCH] dio: reduce the number of cycles

[Li Wang <liwang@redhat.com>]

These two cases (dio29/30) takes a bit long time in dio test, but they're not stress
test, so I suggest reducing the number of cycles.

On my RHEL-7.3 (23G RAM, 24 CPU(s), x86_64) box, it takes almost 9 mins.

  diotest06    1  TPASS  :  Read with Direct IO, Write without
  diotest06    2  TPASS  :  Write with Direct IO, Read without
  diotest06    3  TPASS  :  Read, Write with Direct IO
  diotest06    0  TINFO  :  3 testblocks 1000 iterations with 100 children completed

  real	8m4.805s
  user	71m36.722s
  sys	8m51.649s
