demux: turn some redundant assignments into asserts

Browse Source 
demux_packet.next should not be used outside of demux.c, and in this
case it's a packet that was just passed to demux.c from the outside.

demux_packet.stream is already set by the demuxer, and this is assured
by the add_packet_locked() caller.
