patch 9.1.0043: ml_get: invalid lnum when :s replaces visual selection

Problem:  ml_get: invalid lnum when :s replaces visual selection
          (@ropery)
Solution: substitute may decrement the number of lines in a buffer,
          so validate, that the bottom lines of the visual selection
          stays within the max buffer line

fixes: #13890
closes: #13892
