inet: read sk->sk_family once in inet_recv_error()
[ Upstream commit eef00a82c568944f113f2de738156ac591bbd5cd ]
inet_recv_error() is called without holding the socket lock.
IPv6 socket could mutate to IPv4 with IPV6_ADDRFORM
socket option and trigger a KCSAN warning.
Fixes: f4713a3dfad0 ("net-timestamp: make tcp_recvmsg call ipv6_recv_error for AF_INET6 socks")
