This allows to avoid a typecast.

and this is the easiest way to. It would be alot of messy code we can drop
if it is useless.
As a sideeffect this fixes issue977.

Behaviour only changes if pkt->destuct neither av_destruct_packet,
av_destruct_packet_nofree nor NULL, in which case the new code avoids a double free.

This is consistent with other demuxer's behaviour and avoids a memleak.
It also returns the error from av_get_packet instead of always AVERROR(EIO).
