rtl8139: Do not consume the packet during overflow in standard mode. 



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.
