ipv6: datagram: Refactor flowi6 init codes to a new function

Browse source

Move flowi6 init codes for connected datagram sk to a newly created
function ip6_datagram_flow_key_init().

Notes:
1. fl6_flowlabel is used instead of fl6.flowlabel in __ip6_datagram_connect
2. ipv6_addr_is_multicast(&fl6->daddr) is used instead of
   (addr_type & IPV6_ADDR_MULTICAST) in ip6_datagram_flow_key_init()

This new function will be reused during pmtu update in the later patch.
