[PATCH 2/2] KVM: x86/mmu: Clean up make_huge_page_split_spte() definition and intro

[Sean Christopherson]

Tweak the definition of make_huge_page_split_spte() to eliminate an
unnecessarily long line, and opportunistically initialize child_spte to
make it more obvious that the child is directly derived from the huge
parent.

No functional change intended.
