[dts] [PATCH V1 2/4] fix TestSuite unit_tests_lpm

[Liu, Yong]

Hi gang, test suite is not the right instance to handle hugepage. We 
have planned to let unified module to handle this.
My suggestion is that just increased default FreeBSD huge page memory 
size in framework.
And warning that huge page is insufficient in linux OS.
