KVM: hide KVM_MEMSLOT_INVALID from userspace
Quote Avi's comment:
| KVM_MEMSLOT_INVALID is actually an internal symbol, not used by
| userspace. Please move it to kvm_host.h.
Also, we divide the memlsot->flags into two parts, the lower 16 bits
are visible for userspace, the higher 16 bits are internally used in
kvm
