net/ipv6: Make __inet6_bind static
BPF core gets access to __inet6_bind via ipv6_bpf_stub_impl, so it is not invoked directly outside of af_inet6.c. Make it static and move inet6_bind after to avoid forward declaration. Signed-off-by: David Ahern <dsahern@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>
