conntrackd: complete TCP window scale support
In commit 56817d1c0cc30bcd65c56c2f73634b256603cc4d, I added the
TCP window scale factor support but it was incomplete. We have to
set the IP_CT_TCP_FLAG_WINDOW_SCALE flag to update the td_scale
field via ctnetlink. Check nlattr_to_tcp(...) function in
nf_conntrack_proto_tcp.c for more details.
