Early demux occurs after PRE_ROUTING but before LOCAL_IN.

Otherwise edemux would make little sense since its used to avoid the
routing lookup that decides wheter skb has to be locally delivered or
forwarded. IOW, in NF_INET_LOCAL_IN we've already decided on local
delivery and would not need a 'early' socket lookup any more.
