Philippe Mathieu-Daudé 83ddb3dbba hw/net/net_tx_pkt: Fix overrun in update_sctp_checksum() 
If a fragmented packet size is too short, do not try to
calculate its checksum.

Reproduced using:

                                  -machine q35,accel=qtest -m 32M \

                                  -netdev user,id=net0 \
                                  -qtest stdio
