Roman Khimov 7ee8f9c5d8 network: fix networking stalls caused by stale peers 
We can leak sending goroutines and stall broadcasts because of already gone
peers that happened to be cached by some s.Peers() user (more than 800 of
these can be seen in nodoka log along with (*Server).run blocking on
CMDGetAddr send):
