Checkmk Werk 13758: ipmi_sensors: Fix crash due to incomplete IPMI data

ID: 13758 Title: ipmi_sensors: Fix crash due to incomplete IPMI data Component: Checks & agents Level: 1 Class: Bug fix Version: 2.2.0i1 The check plugin <tt>ipmi_sensors</tt> crashed with <tt>AttributeError ('NoneType' object has no attribute 'startswith')</tt> in case the IPMI datasource started to deliver incomplete data. This can happen for example due to bugs in IPMI firmwares related to SDR caching. With this werk, the corresponding services go stale instead of a crash.
