Fix VM.get_power_state API. On the xend side an integer representation of the power state was being returned instead of a string representation as specified by the XenAPI spec.

On the c-bindings side the marshalling code converts the string representation to an enum value.  A subsequent attempt to convert the enum from a string to an enum was causing a seg fault.
