KVM: x86/mmu: Process only valid TDP MMU roots when aging a gfn range
Skip invalid TDP MMU roots when aging a gfn range. There is zero reason
to process invalid roots, as they by definition hold stale information.
E.g. if a root is invalid because its from a previous memslot generation,
in the unlikely event the root has a SPTE for the gfn, then odds are good
that the gfn=>hva mapping is different, i.e. doesn't map to the hva that
is being aged by the primary MMU.
