KVM: X86/SVM: Use root_level in svm_load_mmu_pgd()

Browse Source 
Use root_level in svm_load_mmu_pg() rather that looking up the root
level in vcpu->arch.mmu->root_role.level. svm_load_mmu_pgd() has only
one caller, kvm_mmu_load_pgd(), which always passes
vcpu->arch.mmu->root_role.level as root_level.
