CLEANUP: mini-clist: simplify nested do { while(1) {} } while (0)

While looking for other occurrences of do { continue; } while (0) I
found these few leftovers in mini-clist where an outer loop was made
around "do { } while (0)" then another loop was placed inside just to
handle the continue. Let's clean this up by just removing the outer
one. Most of the patch is only the inner part of the loop that is
reindented. It was verified that the resulting code is the same.
