Thomas Zimmermann 47248fde59 drm/vmwgfx: Don't double-free the mode stored in par->set_mode 
commit c2d3115538 upstream.

When calling vmw_fb_set_par(), the mode stored in par->set_mode gets free'd
twice. The first free is in vmw_fb_kms_detach(), the second is near the
end of vmw_fb_set_par() under the name of 'old_mode'. The mode-setting code
only works correctly if the mode doesn't actually change. Removing
'old_mode' in favor of using par->set_mode directly fixes the problem.
