From: Vladislav Yasevich <vyase...@redhat.com>
When operation in standard mode, we currently return the size
of packet during buffer overflow. This consumes the overflow
packet. Return 0 instead so we can re-process the overflow packet
when we have room.
This fixes issues with lost/dropped fragments of large messages.
