Eric Dumazet c3658e8d0f tcp: fix possible NULL dereference in tcp_vX_send_reset()
After commit ca777eff51 ("tcp: remove dst refcount false sharing for
prequeue mode") we have to relax check against skb dst in
tcp_v[46]_send_reset() if prequeue dropped the dst.

If a socket is provided, a full lookup was done to find this socket,
so the dst test can be skipped.
