drm/virtio: Call drm_helper_mode_fill_fb_struct() before drm_framebuffer_init()

We want framebuffers to be mostly useable already before
drm_framebuffer_init() get called, and so we will start demanding that
all the interesting format/size/etc. information be filled in before
drm_framebuffer_init(). drm_helper_mode_fill_fb_struct() will do that
for us, so let's make sure it gets called before drm_framebuffer_init().
