KVM: TDX: Skip updating CPU dirty logging request for TDs

Wrap vmx_update_cpu_dirty_logging so as to ignore requests to update
CPU dirty logging for TDs, as basic TDX does not support the PML feature.
Invoking vmx_update_cpu_dirty_logging() for TDs would cause an incorrect
access to a kvm_vmx struct for a TDX VM, so block that before it happens.
