In the code below kvm_vm_ioctl(...) can return --errno != -1 from ioctl call,
but return only checks for -1.
Found during KVM-ARM migration which apperead to go through but was actually
failing getting
memslot dirty bitmap.
static int kvm_physical_sync_dirty_bitmap(....)
{
....
if(kvm_vm_ioctl(s, KVM_GET_DIRTY_LOG, &d) == -1) {
