[dts] [PATCH] tests/kni: fix failures for kni

[Liu, Yong]

Hi Jianbo,
Is there any particular reason for not chose hyper-threading cores?
There're some performance cases are depending on hyper-threading cores. 
If hyper-threading is not enabled on the platform, those cases won't be able to run. 
Could you please clear the reason?

Thanks,
Marvin
