Disallow all flags for KVM-internal memslots as all existing flags require some amount of userspace interaction to have any meaning. In addition to guarding against KVM goofs, explicitly disallowing dirty logging of KVM- internal memslots will (hopefully) allow exempting KVM-internal memslots from the KVM_MEM_MAX_NR_PAGES limit, which appears to exist purely because the dirty bitmap operations use a 32-bit index.
