hyper-v compute driver fails when udpating vm status in _sync_power_states

[Alessandro Pilotti]

When a VM is getting manually shut down on Hyper-V or in case of a host reboot, "nova list" still reports the VM as ACTIVE after nova.compute.manager_sync_power_states runs.

    Fixes a bug in get_info in the Hyper-V Driver

    Fixes Bug #1081070

    When a VM is getting manually shut down on Hyper-V or in case of a host
    reboot, "nova list" still reports the VM as ACTIVE after
    nova.compute.manager_sync_power_states runs.

    The bug is releated to the vm state being incorrectly returned as a
    string.
