avformat/mux: Remove redundant resetting
Now that ff_interleave_add_packet() always returns blank packets, the input packet to ff_interleave_packet_per_dts() will always be blank on return as well (if supplied) and the same goes for interleave_packet() in mux.c. Document these facts and remove the redundant resetting that happened in av_interleaved_write_frame(). The last reference to the (long removed) destruct field that AVPackets once had has been removed as well when updating the documentation of ff_interleave_packet_per_dts().
