KVM: x86/mmu: Rename shadow MMU functions that deal with shadow pages
Rename 2 functions:
kvm_mmu_get_page() -> kvm_mmu_get_shadow_page()
kvm_mmu_free_page() -> kvm_mmu_free_shadow_page()
This change makes it clear that these functions deal with shadow pages
rather than struct pages. It also aligns these functions with the naming
scheme for kvm_mmu_find_shadow_page() and kvm_mmu_alloc_shadow_page().
Prefer "shadow_page" over the shorter "sp" since these are core
functions and the line lengths aren't terrible.
No functional change intended.
