Eric W. Biederman 78b910429e [IPV6] tcp_v6_send_synack: release the destination
This patch fix dst reference counting in tcp_v6_send_synack

Analysis:
Currently tcp_v6_send_synack is never called with a dst entry
so dst always comes in as NULL.

ip6_dst_lookup calls ip6_route_output which calls dst_hold
before it returns the dst entry.   Neither xfrm_lookup
nor tcp_make_synack consume the dst entry so we still have
a dst_entry with a bumped refrence count at the end of
this function.

Therefore we need to call dst_release just before we return
just like tcp_v4_send_synack does.
