[NETNS][IPV6] mcast - fix compilation warning when procfs is not compiled in
When CONFIG_PROC_FS=no, the out_sock_create label is not used because the code using it is disabled and that leads to a warning at compile time. This patch fix that by making a specific function to initialize proc for igmp6, and remove the annoying CONFIG_PROC_FS sections in init/exit function.
