decodebin2: Make sure to remove probes when free GstDecodeGroup
Nothing guarantees that when we free a DecodeGroup the demuxer pads
have already been freed and thus the probes have been removed meaning
that in some case it is possible that the pad probes still get called
*after* the GstDecodeGroup is freed, leading to segfaults (as we use
the freed group in that function).
Sample stack trace when that happens:
