Summary

Why

For instance, it gives a chance to the new backend to refresh the screen. This is needed by the vt_drmfb backend and drm_fb_helper.

This change was lost when I posted changes to reviews.freebsd.org and it broken the amdgpu driver... Thanks to manu@ for reporting the problem and wulf@ to find out the missing change!
