If a Redfish device (for example a Dell iDRAC) listed temperature entries without any data, the service discovery of the host crashed with AttributeError: 'NoneType' object has no attribute 'get'. No services of the host could be discovered.

The discovery now skips such entries and discovers the remaining temperature sensors as before.
