tcp: Actually enforce MAX_CONNS limit

Browse source 
and, given that the connection table is indexed by socket number,
we also need to increase MAX_CONNS now as the ICMP implementation
needs 2^17 sockets, that will be opened before TCP connections are
accepted.

This needs to be changed later: the connection table should be
indexed by a translated number -- we're wasting 2^17 table entries
otherwise. Move initialisation of TCP listening sockets as last
per-protocol initialisation, this will make it easier.
