media: v4l2-mem2mem.c: fix broken links commit 316e730f1d8bb029fe6cec2468fb2a50424485b3 upstream. The topology that v4l2_m2m_register_media_controller() creates for a processing block actually created a source-to-source link and a sink-to-sink link instead of two source-to-sink links. Unfortunately v4l2-compliance never checked for such bad links, so this went unreported for quite some time.
