netfilter: nf_conncount: callers must hold rcu read lock

rcu_derefence_raw() should not have been used here, it concealed this bug.
Its used because struct rb_node lacks __rcu annotated pointers, so plain
rcu_derefence causes sparse warnings.

The major tradeoff is that rcu_derefence_raw() doesn't warn when the caller
isn't in a rcu read section.

Extend the rcu read lock scope accordingly and cause sparse warnings,
those warnings are the lesser evil.
