    libvirt: host update disable/enable report HTTP 400

    When disable/enable host with host-update command, end user will
    get HTTP 400 error even if the host was updated(disabled/enabled)
    successfully.

    The root cause is that after the host was disabled/enabled, nova
    api need depend on host status result to check if the host was
    disabled or enabled, but libvirt driver did not return host status
    to nova api.
