[LTP] [PATCH] io: fix really slow dio_sparse on certain systems

Hi!

Should I merge it with your review tag? I also noticed that I forgot to
update the default value in the test options. I send v2, then we should
merge it if possible because this issue causes test to complete in 4
hours on certain systems.

King regards,
