ipv6: add flowinfo for tcp6 pkt_options for all cases

Browse source

The current implementation of IPV6_FLOWINFO only gives a
result if pktoptions is available (thanks to the
ip6_datagram_recv_ctl function).
It gives inconsistent results to user space, sometimes
there is a result for getsockopt(IPV6_FLOWINFO), sometimes
not.

This patch add rcv_flowinfo to store it, and return it to
the userspace in the same way than other pkt_options.
