drm/vmwgfx: Use correct vmw_legacy_display_unit pointer
[ Upstream commit 1d2c0c565bc0da25f5e899a862fb58e612b222df ]
The "entry" pointer is an offset from the list head and it doesn't
point to a valid vmw_legacy_display_unit struct. Presumably the
intent was to point to the last entry.
Also the "i++" wasn't used so I have removed that as well.
