patch 9.0.2189: Wrong display with 'briopt=sbr' and 'nobreakindent'

Problem:  Wrong display when 'breakindentopt' contains "sbr" and
          'showbreak' and 'nobreakindent' are set.
Solution: Always reset wlv->need_showbreak regardless of the values of
          'breakindent' and 'showbreak', as they aren't checked when
          setting wlv->need_showbreak (zeertzjq)
