KVM: x86/tdp_mmu: Take root types for kvm_tdp_mmu_invalidate_all_roots()

Rename kvm_tdp_mmu_invalidate_all_roots() to
kvm_tdp_mmu_invalidate_roots(), and make it enum kvm_tdp_mmu_root_types
as an argument.

kvm_tdp_mmu_invalidate_roots() is called with different root types. For
kvm_mmu_zap_all_fast() it only operates on shared roots. But when tearing
down a VM it needs to invalidate all roots. Have the callers only
invalidate the required roots instead of all roots.

Within kvm_tdp_mmu_invalidate_roots(), respect the root type
passed by checking the root type in root iterator.
