relayd close before connect

[Alexander Bluhm]

Hi,

Especially with SSL and short data transfers, it could happen that
the client closed before the connection to the server has been
established.  Then the relay closed immediately before transferring
any data.  The solution is to delay the close until the other side
has an event buffer.

ok?
