Jason Andryuk c2af2a4556 fbdev: xen-fbfront: Assign fb_info->device
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: f178e96de7 ("arch: Remove struct fb_info from video helpers")
