Right now, if set configuration fails then the
sink.c:stream_setup_complete seems to consider the stream connected.
So the DBus AudioSink.Connect() call returns without error. But the
stream is not actually ready.
I have a feeling we may want to do some more cleanup, but this patch
does the trick for us.
It is easy to reproduce the problem with the HTC BH S100. If you
quickly disconnect and then reconnect it will return AVDTP set
configuration failed (presumably because it hasn't closed the SEP on
its end yet), but Dbus does not return an error for Connect.
The verbose hcid logs for this problem look like:
