rtl8139: skip offload on short TCP header

TCP Large Segment Offload accesses the TCP header in the packet.  If the
packet is too short we must not attempt to access header fields:

  tcp_header *p_tcp_hdr = (tcp_header*)(eth_payload_data + hlen);
  int tcp_hlen = TCP_HEADER_DATA_OFFSET(p_tcp_hdr);
