tcp: Fix ipv6 checksumming on response packets for real.
Commit 6651ffc8e8bdd5fb4b7d1867c6cfebb4f309512c
("ipv6: Fix tcp_v6_send_response transport header setting.")
fixed one half of why ipv6 tcp response checksums were
invalid, but it's not the whole story.
If we're going to use CHECKSUM_PARTIAL for these things (which we are
since commit 2e8e18ef52e7dd1af0a3bd1f7d990a1d0b249586 "tcp: Set
CHECKSUM_UNNECESSARY in tcp_init_nondata_skb"), we can't be setting
buff->csum as we always have been here in tcp_v6_send_response. We
need to leave it at zero.
Kill that line and checksums are good again.
