[p4] Disable checksum code again 

To make the switch compile. Current error:

*** Starting 2 switches
s1 Starting P4 switch s1.
simple_switch -i 1@s1-eth1 -i 2@s1-eth2 -i 3@s1-eth3 -i 4@s1-eth4 -i 5@s1-cpu-eth0 --pcap=/home/p4/master-thesis/p4app/pcap --thrift-port 9090 --nanolog ipc:///tmp/bm-1-log.ipc --device-id 1 ../p4src/static-mapping.json --log-console >/home/p4/master-thesis/p4app/log/s1.log
P4 switch s1 did not start correctly. Check the switch log file.
