net.server_epoll: Prevent loop attempting to send last data after close
If the connection is closed by the peer, any buffered data is given a
last chance to be sent (see f27b9319e0da). If the connection is Really
closed, no attempt to write will occur, instead epoll will raise the
error flag and :onreadable() will be invoked again, where it will try to
:close() again for the same reason, thus looping until the connection
somehow gets destroyed.
By clearing the _connected flag, the second time it passes :onreadable()
it should go directly to :destroy(), breaking the loop.
Thanks Link Mauve for reporting
