dev_disconnect: support multiple disconnects in the same daemon.

Browse Source 
We currently assume the daemon gives up; gossipd won't, and we want to
test it there too.

This reveals a bug (returning io_close() is bad if the call is to
duplex()), and breaks a test which now continues after dropping a
packet..
