KVM: selftests: Remove useless shifts when creating guest page tables
Remove the pointless shift from GPA=>GFN and immediately back to
GFN=>GPA when creating guest page tables. Ignore the other walkers
that have a similar pattern for the moment, they will be converted
to use virt_get_pte() in the near future.
No functional change intended.
