avformat/audiointerleave: Fix memleak

If ff_interleave_add_packet failed, the content of the newly created
packet new_pkt would leak.

Also, it is unnecessary to zero-initialize a packet that will be put
into av_new_packet lateron as the latter already initializes the packet.
Therefore this has been removed, too.
