When sk_clone() fails, sk_destruct() is called for the new socket.
If the parent socket has SK_FLAGS_TIMESTAMP in sk->sk_flags,
net_disable_timestamp() is called for the child socket even though
net_enable_timestamp() is not called for it.
Let's call net_enable_timestamp() before any failure path in
sk_clone().
Fixes: 704da560c0 ("tcp: update the netstamp_needed counter when cloning sockets")
