    bgpd: Fix v6 connected prefix lookup for connection bind

    The bind-point lookup passed the base of the sockaddr to
    if_lookup_address() instead of the IPv6 address field, so the
    connected prefix was never matched. Pass sin6.sin6_addr instead.

    This corrects an oversight introduced by commit 719313d5dd ("bgpd:
    Ensure that BGP binds to connection addresses that it can").
