l2tp: don't use tunnel socket sk_user_data in ppp procfs output 

l2tp's ppp procfs output can be used to show internal state of
pppol2tp. It includes a 'user-data-ok' field, which is derived from
the tunnel socket's sk_user_data being non-NULL. Use tunnel->sock
being non-NULL to indicate this instead.
