KVM: x86: don't reset root in kvm_mmu_setup()
Here is the code path which shows kvm_mmu_setup() is invoked after
kvm_mmu_create(). Since kvm_mmu_setup() is only invoked in this code path,
this means the root_hpa and prev_roots are guaranteed to be invalid. And
it is not necessary to reset it again.
kvm_vm_ioctl_create_vcpu()
kvm_arch_vcpu_create()
vmx_create_vcpu()
kvm_vcpu_init()
kvm_arch_vcpu_init()
kvm_mmu_create()
kvm_arch_vcpu_setup()
kvm_mmu_setup()
kvm_init_mmu()
This patch set reset_roots to false in kmv_mmu_setup().
