'dc_stream_release()' may be called twice. Once here, and once below in the
error handling path if we branch to the 'fail' label.
Set 'new_stream' to NULL, once released to avoid the duplicated release
function call.

Maybe the 'goto fail' at line 7745 should be turned into a 'return ret'
instead. Could be clearer.
No Fixes tag provided because I've not been able to dig deep enough in the
git history.
