drm/msm/dpu: add missing break statement for update_pending_flush_wb()

Add missing break statement for dpu_hw_ctl_update_pending_flush_wb().
Otherwise this leads to below build warning.

drivers/gpu/drm/msm/disp/dpu1/dpu_hw_ctl.c:273:2:
warning: unannotated fall-through between switch labels
           default:
           ^
drivers/gpu/drm/msm/disp/dpu1/dpu_hw_ctl.c:273:2:
note: insert 'break;' to avoid fall-through
           default:
           ^
           break;
