[PATCH 4/7] KVM: nVMX: Rename nested_ept_get_cr3() to nested_ept_get_eptp()

[Sean Christopherson]

Rename the accessor for vmcs12.EPTP to use "eptp" instead of "cr3".  The
accessor has no relation to cr3 whatsoever, other than it being assigned
to the also poorly named kvm_mmu->get_cr3() hook.

No functional change intended.
