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:

  $ cat << EOF | qemu-system-i386 -display none -nodefaults \
                                  -machine q35,accel=qtest -m 32M \
