When the packet size is known in advance like here, one can avoid
an intermediate buffer for the packet data.

Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
ff_alloc_packet2() call (for the actual packets, not this end-of-stream
packet), yet the size known in advance is not exact.
