net: fix build without CONFIG_SYSCTL definition
Earlier commit 316cdaa1158a ("net: add option to not create fall-back tunnels in root-ns as well") removed the CONFIG_SYSCTL to enable the kernel-commandline to work. However, this variable gets defined only when CONFIG_SYSCTL option is selected. With this change the behavior would default to creating fall-back tunnels in all namespaces when CONFIG_SYSCTL is not selected and the kernel commandline option will be ignored.
