From ovs2.7 onwards, vswitchd will be restarted when dpdk-init
flag is set to true. In the current version of the first-boot, we are
enabling dpdk before setting the kernel args and reboot. So, huge
pages will not be available. It will fail the vswitchd restart during
the dpdk-init.

But later when kernel args are applied and rebooted, it will all work
fine. And all the ovs configurations will be applied correctly. But
this causes atleast a few set of logs related to vswtichd failure
before the restart. Though this does not harm, we need to be aware of
this behavior as analyzing logs will create questions around it.
