Probing xen-fbfront faults in video_is_primary_device(). The passed-in
struct device is NULL since xen-fbfront doesn't assign it and the
memory is kzalloc()-ed. Assign fb_info->device to avoid this.
This was exposed by the conversion of fb_is_primary_device() to
video_is_primary_device() which dropped a NULL check for struct device.
Fixes: f178e96de7f0 ("arch: Remove struct fb_info from video helpers")
