KVM: nVMX: Rename nested_ept_get_cr3() to nested_ept_get_eptp()

Browse Source 
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.
