netfilter: conntrack: gre: convert rwlock to rcu
We can use gre. Lock is only needed when a new expectation is added.
In case a single spinlock proves to be problematic we can either add one
per netns or use an array of locks combined with net_hash_mix() or similar
to pick the 'correct' one.
But given this is only needed for an expectation rather than per packet
a single one should be ok.
