[TCP]: Restore SKB socket owner setting in tcp_transmit_skb().
Revert 931731123a103cfb3f70ac4b7abfc71d94ba1f03
We can't elide the skb_set_owner_w() here because things like certain
netfilter targets (such as owner MATCH) need a socket to be set on the
SKB for correct operation.
Thanks to Jan Engelhardt and other netfilter list members for
pointing this out.
