patch 9.1.0785: cannot preserve error position when setting quickfix list 
Problem:  cannot preserve error position when setting quickfix lists
Solution: Add the 'u' action for setqflist()/setloclist() and try
          to keep the closes target position (Jeremy Fleischman)

fixes: #15839
closes: #15841
