Hans Verkuil 6bda7073f3 media: v4l2-subdev: fix regression in check_pad() 
sd->entity.graph_obj.mdev can be NULL when this function is called, and
that breaks existing drivers (rcar-vin, but probably others as well).

Check if sd->entity.num_pads is non-zero instead since that doesn't depend
on mdev.
