ipv6: lock socket in ip6_datagram_connect()
[ Upstream commit 03645a11a570d52e70631838cb786eb4253eb463 ]
ip6_datagram_connect() is doing a lot of socket changes without
socket being locked.
This looks wrong, at least for udp_lib_rehash() which could corrupt
lists because of concurrent udp_sk(sk)->udp_portaddr_hash accesses.
