net: fix cipso packet validation when !NETLABEL
[ Upstream commit f2e5ddcc0d12f9c4c7b254358ad245c9dddce13b ]
When CONFIG_NETLABEL is disabled, the cipso_v4_validate() function could loop
forever in the main loop if opt[opt_iter +1] == 0, this will causing a kernel
crash in an SMP system, since the CPU executing this function will
stall /not respond to IPIs.
This problem can be reproduced by running the IP Stack Integrity Checker
(http://isic.sourceforge.net) using the following command on a Linux machine
connected to DUT:
"icmpsic -s rand -d <DUT IP address> -r 123456"
wait (1-2 min)
