Sakari Ailus de49c285a3 [media] media: Check for active links on pads with MEDIA_PAD_FL_MUST_CONNECT flag ...

Do not allow streaming if a pad with MEDIA_PAD_FL_MUST_CONNECT flag is not
connected by an active link.
This patch makes it possible to avoid drivers having to check for the most
common case of link state validation: a sink pad that must be connected.
