[PATCH 2/2] hw/nvme: support smart AEN

[zhenwei pi]

Support smart AEN on controller side, if the guest side enables this
feature, after injecting smart critical warning, also raise AER.

This can be tested by:
virsh qemu-monitor-command vm '{ "execute": "qom-set", "arguments":
  { "path": "/machine/peripheral/nvme0",
  "property": "smart_critical_warning", "value":1 } }'
