Remove calls to MediaCodec#stop from AVDA

Remove calls to MediaCodec#stop from AVDA

Previously there were cases where MediaCodec#stop would be called while
the MediaCodec was in a broken state, which results in hitting a CHECK.
In AVDA we don't actually need to call stop() because it's always called
right before deleting the MediaCodec. This replaces those calls with
explicit deletion.
