patch 9.0.1607: screenpos() returns wrong row with diff filler lines

Browse Source 
Problem:    screenpos() returns wrong row with diff filler lines.
Solution:   Only add filler lines when appropriate.  Also don't add the
            'smoothscroll' marker when w_skipcol is zero. (closes #12485,
            closes #12484)
