Subject: [PATCH 1/2] connector: fix #include <linux/cn_proc.h>

Including <linux/cn_proc.h> first line doesn't work because of missing
forward declaration:

In file included from kernel/foo.c:1:
include/linux/cn_proc.h:32:47: error: ‘struct task_struct’ declared inside parameter list will not be visible outside of this definition or declaration [-Werror]
   32 | static inline void proc_fork_connector(struct task_struct *task)
      |                                               ^~~~~~~~~~~
