[PATCH v1 4/4] KVM: selftests: Replace previously used vm_get_stat() to macro

[Manali Shukla <manali.shukla@amd.com>]

Previous patch converts vm_get_stat() to macro and adds a concatenation
trickery to generate compilation error if the stat doesn't exist.

Improve nx_huge_pages_test.c and dirty_log_page_splitting_test.c based
on the macro.

Compile tested both the selftests.
