tcp: fix mtu on server sockets again (thans mycroftix)
for incoming connection, we used s->laddr to lookup the interface
for the incoming call, but this does not work when the announce
address is tcp!*!123, then s->laddr is all zeros "::". instead,
use the incoming destination address for interface mtu lookup.
thanks mycroftix for troubleshooting!
