Kuniyuki Iwashima 364f997b5c ipv6: Fix data races around sk->sk_prot. 
Commit 086d49058c ("ipv6: annotate some data-races around sk->sk_prot")
fixed some data-races around sk->sk_prot but it was not enough.

Some functions in inet6_(stream|dgram)_ops still access sk->sk_prot
without lock_sock() or rtnl_lock(), so they need READ_ONCE() to avoid
load tearing.

Fixes: 1da177e4c3 ("Linux-2.6.12-rc2")
