Fix bug #11367 with assertion violation during vertical motion in egg.el.

 src/xdisp.c (pos_visible_p): If already at a newline from the
 display string before the 'while' loop, don't walk back the glyphs
 from it3.glyph_row.  Solves assertion violation when the display
 string begins with a newline (egg.el).
