Subject: [PATCH v7 11/23] KVM: x86/mmu: Replace vcpu with kvm in kvm_mmu_alloc_shadow_page()

From: David Matlack <dmatlack@...gle.com>

The vcpu pointer in kvm_mmu_alloc_shadow_page() is only used to get the
kvm pointer. So drop the vcpu pointer and just pass in the kvm pointer.

No functional change intended.
