drm/vmwgfx: correct fb_fix_screeninfo.line_length
commit aa6de142 upstream. Previously, the vmwgfx_fb driver would allow users to call FBIOSET_VINFO, but it would not adjust the FINFO properly, resulting in distorted screen rendering. The patch corrects that behaviour. See https://bugs.gentoo.org/show_bug.cgi?id=494794 for examples.
