Avoid leaving garbage on screen when using 'raise' display property

Browse source 
* src/xdisp.c (display_line): Reset voffset value of the iterator
when it hits ZV, to avoid "inheriting" it to glyph rows past ZV,
which then leaves stuff on screen that needs to be cleared by
redisplay.  (Bug#25855)
