KVM: Disallow all flags for KVM-internal memslots
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.
