[PATCH v6] cgroup: net_cls: Move sock_update_classid() declaration to cls_cgroup.h

[Daniel Wagner]

From: Daniel Wagner <daniel.wagner@xxxxxxxxxxxx>

The two users of sock_update_classid() are net/socket.c and
drivers/net/tun.c. socket.c includes cls_cgroup.h already. Update
tun.c to inlcude the header.
