qemu-kvm in zesty proposed failed with KVM_GET_DEVICE_ATTR failed error

This is a potential regression for ARM64 qemu-kvm package (1:2.8+dfsg-3ubuntu2.8).

With qemu-kvm updated from 1:2.8+dfsg-3ubuntu2.7, the kvm-unit-test in our test suite will fail with:
  Unexpected error in kvm_device_access() at /build/qemu-2b6oyQ/qemu-2.8+dfsg/kvm-all.c:2151:
  qemu-system-aarch64: KVM_GET_DEVICE_ATTR failed: Group 6 attr 0x000000000000c664: No such device or address
  QEMU Aborted

Steps:
 1. Deploy a ARM64 zesty system
 2. git clone https://git.kernel.org/pub/scm/virt/kvm/kvm-unit-tests.git
 3. cd kvm-unit-tests
 4. ./configure; make
 5. sudo ./run_tests -v
 6. Enable proposed and upgrade the qemu-kvm package, repeat step 5
