IPV6 - Attempt to fix tcp46 compatibility listen sockets
* When creating the accepted socket via the syncache, if the
listen socket is INET6 but allows compatibility connections
the inp created via sonewconn() will probably set IN6P_IPV6_V6ONLY.
This flag must be cleared if the incoming connection is
actually IPV4, otherwise tcp6_soport() will not properly
fall through to tcp_soport().
* NOTE: Even though the connection is IPV4 the socket's protocol
is copied from the listen socket which is INET6. This seems
to work ok but it isn't ideal.
* When connecting make sure that IPV6 connections use cpu 0 for
now (we don't have a proper hash for IPV6 addresses yet).
