net: ip: on synack copy local/remote data prior to net_tcp_register

Browse source 
When TCP SYNACK is received we register the connection via the
net_tcp_register function.  During this call several errors are
generated concerning local and remote address information not
being set.

Let's copy the local and remote address data prior to this call.
