KOMA-Classes (scrbook, scrreprt, ... ): Disable chapter separation in \listoffigures and \listoftables

According to table 3.20 in the KOMA-Script manual the following snippet added to the preamble will solve the issue

\KOMAoptions{listof=nochaptergap}

alternatively you can pass this option directly to the koma-documentclass

\documentclass[listof=nochaptergap]{scrreprt}

It's explained in section 3.16 of the manual of KoMa-Script:

\documentclass
 [... other options ...,
  chapteratlists=0pt]{scrreprt}
