net/ipv4: Update ip_tunnel_metadata_cnt static key to modern api
No changes in refcount semantics -- key init is false; replace static_key_slow_inc|dec with static_branch_inc|dec static_key_false with static_branch_unlikely Signed-off-by: Davidlohr Bueso <dbueso@suse.de> Signed-off-by: David S. Miller <davem@davemloft.net>
