obs-outputs: Fix AV1 header parser adding ref count to data

The header packets are only used within the rtmp-output and do not need
or use the ref counter as the data is manually free'd directly.

The presence of this ref counter causes a crash on *nix platforms due to
our memory alignment hack attempting to free memory but reading the
wrong offset due to the ref counter being there rather than the
alignment offset.
