Check_MK Werk 6967: Initialize step value for unknown metrics in rrddata columns

ID: 6967 Title: Initialize step value for unknown metrics in rrddata columns Component: Livestatus Level: 1 Class: Bug fix Version: 1.6.0i1 When unknown metrics were queried via rrddata Livestatus columns, the step value was not initialized, so a more or less random value was returned. Valgrind was of course unhappy about this, too. This has been fixed, and the step value is now zero under such circumstances.
