[PATCH 04/23] KVM: x86/mmu: Rename shadow MMU functions that deal with shadow pages

[David Matlack <dmatlack@xxxxxxxxxx>]

Rename 3 functions:

  kvm_mmu_get_page()   -> kvm_mmu_get_sp()
  kvm_mmu_alloc_page() -> kvm_mmu_alloc_sp()
  kvm_mmu_free_page()  -> kvm_mmu_free_sp()

This change makes it clear that these functions deal with shadow pages
rather than struct pages.
